Use the inverse sine function on a calculator.
arcsin (0.88) = 1.08 radians
3/4 is 75% so the answer is 75% out of 100
Hope that helps!:)
Answer:
See Below
Step-by-step explanation:
Thankfully, all the parts you need are given.
First, find the surface of one triangle
A = 1/2bh
A = 1/2(15)(9)
A = 1/2(135)
A = 67.5
Multiply by 4 to get the sum of all the sides.
67.5(4) = 270
Now find the surface area of one square
A = bh
A = (15)(15)
A = 225
multiply by 5 to get all 5 sides
225(5) = 1125
Add sums together
1125 + 270 = 1395
The answer is D because the two points are in x-value -1 and 3
