Respuesta :
A skateboarding ramp is 10 in. high and rises at an angle of 15°-The base of the ramp is 37.3 inches long.
Step-by-step explanation:
Let x represent the length of base of ramp.
It is given that a skateboarding ramp is 10 in high and it rises at an angle of 15 degrees. We need to find the base of the skateboard.
The height of ramp, the base of ramp and angle of elevation make a right triangle with ground, where, 10 inch is opposite side and base of ramp is adjacent side of angle of elevation.
we Know that
tan=opposite/adjacent
tan(15°)=10/x
x=10/tan(15°)
x=10/0.267949192
x=37.32
Therefore, the base of ramp is 37.3 inches long.
The length of the base to the nearest inch is 37 inches
Angle of elevation and depression
Given the following parameters from the questions:
Height of the ramp = 10in
angle of elevation = 15degrees
Using the SOH CAH TOA identity
tan 15 = opp/adj
tan 15 = 10/B
B = 10/tan15
B = 10/0.2679
B = 37 inches
Hence the length of the base to the nearest inch is 37 inches
