for right angle triangle ABD
BD^2 = 36 + 64 = 100
BD = 10
use sine law
sin (29) / BD = sin (x)/ DC
sin (29)/ 10 = sin x/ 13
sin x = 13 sin (29)/ 10
First solve for BD:
a² + b² = c²6² + 8² = BD²BD² = 36 + 64BD² = 100BD = √100BD = 10Then use sine rule:
sin(A)/a = sin(B)/binsert values

The equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.
What is the equation of line?The equation of the line is the way of representation of a line in the equation form.
The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
The formula to find equation of line is,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
Here, x and y are the coordinate and subscript (1,2) used for the first and second point.
The points from which the line passes through are (2,5) and (-2,-3). Put the values,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
(y-(-2))={(-3-5)/(-2-2)}(x-2)
y+2={-8/-4}(x-2)
y+2=2(x-2)
y+2=2x-4
y=2x-4-2
y=2x-6
Thus, the equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.

give two coterminal angles (one positive and one negative) and the reference angle. 290
Answers
The coterminal angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.
What is coterminal angles?Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
We have an angle:
290 degree
To find the coterminal angle, add and subtract 360 degree in the angle 290 degree.
Coterminal angle = 290 + 360 = 650 degree
= 290 - 360 = -70 degree
Reference angle = 360 - 290 = 70 degree
Thus, the coterminal angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.

In order to find the area of this triangle, we need to find the base and height of the triangle
the base of the triangle is 7 units long and the height of the triangle is 4 units high
Formula for area of triangle: Base x Height x 1/2
7 x 4 x 1/2 --> 28 x 1/2 --> 14
So, the area of this triangle is 14
Now the question is asking to find the area by forming a parallelogram
All you have to do for this is duplicate that same triangle, and mirror it upside down
Then all you would have to do is find the Base and the Height and multiply them together
Put these fractions in order of size, smallest to largest.

Ravi buys lunch at a restaurant.
An 8% sales tax is added, and he tips the waiter 20% of the cost of the food.
Ravi pays a total of $17.92 for his lunch, including tax and tip.
What is the price of Ravi's lunch, before tax and tip?
Answers
The price of Ravi's lunch, before tax and tip was added to the total cost of the meal is $13.19.
What is the price of the lunch?Both the tax and the tip paid would increase the cost of the meal. Thus, their dollar value has to be subtracted from the total amount he pays.
Value of the lunch after the tip has been removed = (1 - 0.2) x 17.92 = $14.34
Value of the lunch after the tax has been removed = (1 - 0.08) x $14.34 = $13.19

The graphed inequality can be written as:
y < -(4/3)*x + 5
How to find the inequality?
At first, we can notice two things, the shaded region is below the line, and the line is a dashed line, so we know that the inequality will be:
y < linear equation.
The linear equation is something like:
y = a*x + b
By looking at the graph, we can see that the line passes through (0, 5) and (3, 1).
So the y-intercept is 5.
And the slope is:
a = (1 - 5)/(3 - 0) = -4/3
So the linear equation is:
y = -(4/3)*x + 5
And the inequality is:
y < -(4/3)*x + 5

A 0.25 kg baseball is in contact with a bat for 0.0075 s and exerts a force of 18,500 n. what impulse is delivered to the ball? 33 kg • meters per second. 140 kg • meters per second. 4600 kg • meters per second. 74,000 kg • meters per second.
Answers
The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
What is Impulse?An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
Mass of baseball m = 0.25kgTime of contact t = 0.0075sForce exerted F = 18500N = 18500kgm/s²Impulse ΔP = ?We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s
Therefore, the impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.

The correct equation is 3b - 6 = 45. You get this by saying the books (b) are 3 dollars each (3b) and you are getting a discount of 6 dollars off (- 6). The total after the discount is 45 dollars. You know have to solve this equation for b (the number of books) to get the answer. When you solve this equation, you get b = 17.
Answer:
3b - 6 = 45 and b = 17
Step-by-step explanation:
3b - 6 = 45 is your equation you get
3b is how many books you bought and the price multiplied by one another, then subtracting 6 gives you the discounted price which is 45
3b - 6 = 45
+6 +6
3b = 51
/3 /3
b = 17
a book costs 17 dollars.

Express a^2 - 4 as a difference of two squares

=> x = 125/5
=> x = 25°
Now the angles are ,
2x = 2(25)=50° &
3x = 3(25) = 75°
Hope this helps you :)
Have a good day :)
Answer:
Angles of the triangles are 55° , 50° , 75°
Step-by-step explanation:
Exterior angle property of triangle:The exterior angle of a triangle equals the sum of opposite interior angles.
Ratio of interior opposite angle = 2 : 3
Interior opposite angles are 2x , 3x
2x + 3x = 125
5x = 125
x = 125/5
[tex]\boxed{x = 25}[/tex]
2x = 2*25 = 50°
3x = 3*25 = 75°
Let the third angle of the triangle = y
Sum of all angles of triangle = 180
50 + 75 + y = 180
125 + y = 180
y = 180 - 125
y = 55°
Angles of the triangles are 55° , 50° , 75°
