Answer: The tall cliff is 118.20 feet tall and the short cliff is 70.32 feet tall.
If you draw a picture with 2 cliffs and a river in the middle, you have find 2 right triangles. In each triangle the adjacent side to our known angle is the river of 90 feet. And the unknown side is the opposite leg.
Therefore, we can set up a tangent equation.
From the top of the short cliff to the top of the tall cliff, we can right and solve the following trig equation:
tan(28) = x /90
x = 47.88
From the top of the short cliff to the bottom, we can right and solve the following trip equation.
tan(38) = x/90
x = 70.32
The 70.32 is also the height of the short cliff. And adding the two answers together will give you the height of the tall cliff.
Answer:
10
Step-by-step explanation:
f(-3)=-2(-3)+4=6+4=10
Same idea as last time only the similar angles are 92 and 92. Thus your anwser: 92

Answer:
She spent 8 hours with the bike. She did rent the bike.
Step-by-step explanation:
The $11 fee is only a one time payment. The $5 is every hour so 5x8 is 40+11 is 51.
