Answer: This is basic trig man, So I can help you here. First thing you need is a calculator that can do sin cos and tan, ti-84 would work best. You need to use the sin cos and tan formulas to find the edge lengths of the side. heres a helppful tip to remeber the proper way to use the formulas. SOH-CAH-TOA or sin(angle measure)= Opposite side to that angle measure divided by the hypotenuse cos(angle measure)= adjacent side (the side next to the angle) divided by the hypotenuse. and TOA or Tan(angle measure)=Opposite divided by adjacent.
Step-by-step explanation: This is a mix of Special right triangles and trig. You now know how to do the trig, look up special right triangles 60 30 90 and 90 45 45, it should show you how to do the rest of the math, since I don't recall the formulas for this off the top of my head. I am not just giving you the answers for two reasons, 1 it would take tooo long and I am already doing a quiz, which I have five minutes left to complete, and B If you cant do this for yourself you will fail the final for your course.

Answers
Answer:
x = 45
Step-by-step explanation:
x + 45 + 2x = 180
3x + 45 = 180
3x = 135
x = 45
Answer:
x = 45
Step-by-step explanation:
We know that the three angles of a triangle add up to 180. So we can add all the points equal to 180 to find the value of x.
a + b + c = 180
45 + x + 2x = 180
Combine terms.
45 + 3x = 180
Subtract 45 from both sides.
3x = 135
Divide both sides by 3 to get
x = 45.
To prove this, put x into the original addition of the angles.
45 + x + 2x = 180
Substitute 45 into x.
45 + 45 + 2(45) = 180
Multiply 2 and 45.
45 + 45 + 90 = 180
Add terms.
180 = 180.

The diameter of the inner circle is [tex]d=14\ m[/tex]
thickness of the strip is [tex]t=2\ m[/tex]
So, the radius of inner circle is [tex]r=7\ m[/tex]
Radius of the outer circle [tex]R=7+2=9\ m[/tex]
Area of the shaded region is the difference of the area of outer circle and inner circle.
[tex]\Rightarrow \pi R^2-\pi r^2\\\Rightarrow \pi (9^2-7^2)\\\Rightarrow 3.142\times 32\\\Rightarrow 100.5\ m^2[/tex]
hence, option (a) is correct.

Twice a number increased by 12 is 20. What is the number?
Answers
Answer:
2x+12 = 20
x = 4
Step-by-step explanation:
Twice a number = 2x
increased by 12 = +12
Format:
2x + 12 = 20
Solve
Subtract 12 from both sides
2x + 12 - 12 = 20 - 12
2x = 8
divide both sides by 2
2x/2 = 8/2
x = 4

Answer:
B
Step-by-step explanation:
Slope intercept form - y = mx + b
where m = slope and y = slope
We are given the slope (-3)
so we would have y = -3x + b
We want to find the y intercept or "b"
To do so we plug in the x and y values of the given coordinate
5 = -3 ( 2 ) + b
we then solve for b
step 1 simplify -3 * 2 = -6
5 = -6 + b
add 6 to each side
5 + 6 = 11
-6 + 6 cancels out
we're left with b = 11
So the equation would be y = -3x + 11

The planet venus is on average 2.5x10^7 kilometers from earth. The planet mars is on average 2.25x10^8 kilometers from earth. What is the average distance from venus to mars?
Answers
Answer:
The average distance from venus to mars is 2.5x10⁸ kilometers.
Step-by-step explanation:
We know:
d₁: average distance between venus and earth = 2.5x10⁷ km
d₂: average distance between mars and earth = 2.25x10⁸ km
We can find the average distance from venus to mars as follows:
[tex] d_{t} = d_{1} + d_{2} [/tex]
First, we need to equal the base power 10 so we can sum both distances:
[tex]2.25 \cdot 10^{8} = 2.25 \cdot 10^{7} \times 10 = 22.5 \cdot 10^{7} km[/tex]
Now, average distance:
[tex]d_{t} = 2.5 \cdot 10^{7} + 22.5 \cdot 10^{7} = (2.5 + 22.5) \cdot 10^{7} = 25 \cdot 10^{7} km = 2.5 \cdot 10^{8} km[/tex]
Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.

Jane borrowed $200 from her parents to buy a video game system. She has agreed to pay them back $35 each week. Which equation represents the amount of money Jane still owes her parents, p, after w weeks?
Answers
Answer:
p = 200 - 35w
Step-by-step explanation:
Let's represent
Number of weeks = x
Amount of money Jane still owes her parents = p
From the above question, we are told:
Jane borrowed = $200
She agreed to pay = $35 each week. Therefore, the equation that represents the amount of money Jane still owes her parents, p, after w weeks is written as:
p = $200 - $35 × w
p = 200 - 35w
