Answer:

MN║OP

Step-by-step explanation:

From the picture attached,

MP and OP are the two lines and OT is a transversal intersecting these lines at R and S.

Angles on the same side of transversal OT measure the same as 45°

By the converse of corresponding angles theorem,

"If the corresponding angles formed by the transversal with the lines, are equal in measure, then the lines are parallel."

Therefore, MN║OP is the answer.

How do you write 23/25 as a percentage

Answers

23/25 as a percentage is 92%
Hope this helps (:

Answer:

92%

Step-by-step explanation:

a Percent is equal to 1/100

so we need to make the denominator 100

so you multiply both the denominator and numerator by 4

4*23=92

4*25=100

92/100

which is also 92%

Suppose that Sin(θ)=5/13 and cos(θ)=-12/13. Find the value of tan(θ), cot (θ), CSC (θ), and sec (θ). Find the value of tan(2θ)
I know the values are tanθ=5/12, cscθ=13/5, secθ=13/-12 and cotθ=-12/5 but I don't know how to find tan(2θ)

Answers

Answer:

Because θ lies in quadrant II, 2θ must lie in quadrant IV. This means the tangent of 2θ is negative.

The adjacent side to θ is 7 because √(25²-24²)=7, so tanθ=7/24.

The double angle formula for tangent is tan 2θ = (2 tan θ) / (1 − tan² θ).

Substituting the value for tanθ in and keeping in mind that this is in quadrant IV, we get tan 2θ = -(2(7/24)/(1-(7/24)²)).

Simplified, this becomes tan 2θ = -336/527.

Therefore, the answer is C. -336/527.

The sum of the digits of certain two-digit number is 9. Reversing its digits increase the number by 45. Find the number.
A) 36
B) 30
C) 27
D) 26

Answers

the answer would be A

If the original number can be written as ab, where a is the digits in the tens place and b is in the ones place, then it can be expanded as

10a + b

where a and b are chosen from {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. The sum of the digits is 9, so

a + b = 9

Reversing the digits gives the number ba, or

10b + a

which is larger than ab by 45, so

10b + a = (10a + b) + 45

-9a + 9b = 45

a - b = -5

Solve for a and b :

(a + b) + (a - b) = 9 + (-5)

2a = 4

a = 2

Then

a + b = 9

2 + b = 9

b = 7

So the original number if (C) 27.

Let |u| = 10 at an angle of 45° and |v| = 13 at an angle of 150°, and w = u + v. What is the magnitude and direction angle of w?

a) |w| = 9.4; θ = 72.9°
b) |w| = 9.4; θ = 107.1°
c) |w| = 14.2; θ = 72.9°
d) |w| = 14.2; θ = 107.1°

Answers

Answer:

Step-by-step explanation:

Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.

Given that, |u| = 10 at an angle of 45° and |v| = 13 at an angle of 150°.

We need to find magnitude and direction angle of w.

We have, w = u + v, θ=45° and ϕ=150°.

[tex]u_{x}[/tex]=|u|cosθ=10cos45°=7.071

[tex]u_{y}[/tex]=|u|sinϕ=[tex]u_{y}[/tex]=|10sin45°=7.071

[tex]v_{x}[/tex]=|v|cosθ=13cos150°=-11.25833

[tex]v_{y}[/tex]=|v|sinϕ=[tex]v_{y}[/tex]=13sin150°=6.5

Using this information, we get

[tex]R_{x} =u_{x} +v_{x}[/tex]=7.071-11.25833=-4.18733

[tex]R_{y} =u_{y} +v_{y}[/tex]=7.071+6.5=13.571

Direction angle=[tex]tan^{-1}[/tex](Ry/Rx)

Direction angle=[tex]tan^{-1}[/tex](13.571/-4.18733)

=-72.8239 or 107.1476≈107.1

Now, [tex]|w|=\sqrt{(|u|cos \theta +|v|cos \phi )^{2}+(|u|sin \theta +|v|sin \phi )^{2}}[/tex]

=[tex]|w|=\sqrt{(10cos45\textdegree +13cos150\textdegree )^{2}+(10sin 45\textdegree+13sin150\textdegree)^{2}}=14.2026[/tex]

Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.

12y=17-9x and -4y-3x=31 solve by elimination

Answers

Answer:

0 ≠ 110

No solution

Step-by-step explanation:

Solve by Addition/Elimination

12y = 17 − 9x and −4y − 3x = 31

Reorder 17 and −9x. 12y = −9x + 17

−4y − 3x = 31

Add 9x to both sides of the equation.

12y + 9x = 17

−4y − 3x = 31

Reorder the polynomial.

9x + 12y = 17

−4y − 3x = 31

Reorder the polynomial.

9x + 12y = 17

−3x − 4y = 31 9x + 12y = 17

Multiply each equation by the value that makes the coefficients of x opposite.

9x + 12y = 17

(3) ⋅ (−3x − 4y) = (3) (31)

Simplify (3) ⋅ (−3x − 4y).

Apply the distributive property.

9x + 12y = 17

3 (−3x) + 3 (−4y) = (3) (31)

Multiply −3 by 3. 9x + 12y = 17

−9x + 3 (−4y) = (3) (31)

Multiply −4 by 3. 9x + 12y = 17

−9x − 12y = (3) (31)

Multiply 3 by 31. 9x + 12y = 17

−9x − 12y = 93

Add the two equations together to eliminate x from the system.

9x+12y=17

+−9x−12y=93

0=110

Since 0 ≠ 110, there are no solutions. No solution

I’m not how to explain this but bear with me.

The supplement of measure of 164 degree angle is 16 degrees.
The bigger triangle is a right triangle, meaning it has an angle of 90 degrees.

We can find the big angle on the top by adding both angles we know of together and subtract that from 180 degrees because all interior angles of a triangle add up to 180 degrees:
180 - (90 + 16) = 180 - 106 = 72 degrees

According to the picture, the angle appears to be bisected, meaning it has been divided into two congruent angles.
Take the 72 degree angle and divide it by 2 to get the measure of each angle. Each angle is 36 degrees.

Finally, add the measures of the 36 degree and 16 degree angle and subtract that from 180 degrees to get the measure of the unknown angle (the value of x).
180 - (36 + 16) = 180 - 52 = 128 degrees

x = 128 degrees
