Answer:
The height of tree house is 70.71 feet
Step-by-step explanation:
We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground
Refer the attached figure
Length of rope AC = Hypotenuse =100 feet
The top of a tree house to the ground forms a 45∘ angle of elevation from the ground =
We are supposed to find the height of tree house i.e.AB = Perpendicular
So, Using trigonometric ratio
Hence The height of tree house is 70.71 feet
Answer:
D
Step-by-step explanation:
To find the y- intercept, let x = 0 in the equation
Given
f(x) = - - 1, then
f(0) = - - 1 = -
- 1 ← y- intercept,
(0, - - 1 ) ← coordinates of y- intercept
