Question

Michael is constructing a boat ramp. He knows that the angle of elevation of the ramp is 30°. If the distance from the bottom of the boat ramp to the top of the boat ramp is 50 feet, what is the height of the boat ramp?

Answer 1

25 feet

Explanation:

Answer 2

The height of the boat ramp is 25 feet

Explanation:

we know that

In the right triangle ABC

Let

h the height of the boat ramp in feet

see the attached figure

`sin(30^o)=(h)/(50)` ----> SOH (opposite side divided by the hypotenuse)

solve for h

`h=sin(30^o)(50)=25\ ft`
