95.7942857 pie form hope this is right got it off the internet so yeah
Answer:
We have sinθ = 12/13
The method here is to figure out the value of θ
Using a calculator sin^(-1)(12/13) =67.38°
67.38° is in quadrant 1 so we must substract 67.38° from 180° wich is π
- 180-67.38= 112.61° ⇒ θ= 112.61°
Now time to calculate cos2θ and cosθ using a calculator
- cosθ = -5/13
- cos2θ = -0.7
The values we got make sense since θ is in quadrant 2 and 2θ in quadrant 3
Answer:

Step-by-step explanation:
Answer:
75%
Step-by-step explanation:
It went down by 3 so,
4-1=3
4 * 75% or 0.75=3
Answer:
about 89.27 inches
Step-by-step explanation:
This is a right triangle question
c^2 = a^2 + b^2
c^2 = 15^2 + 88^2
c^2 = 225 + 7744
c^2 = 7969
Take the square root of both sides
c = 89.2692556259
c ≈ 89.27 inches
