Question

The distance between the end of a lamppost’s shadow and the top of the lamppost is 22 feet. The angle measure of the shadow is 15°. How tall is the lamppost to the nearest tenth of a foot?

Answer 1

haha very easy simply treat it as a triangle... using pythagoras theorem we can solve it..

Answer 2

sin theta = o/h
sin15 = x/22
22sin15=x
x=5.7ft

Answer 3

so we can use the sine function to solve for the opposite side.

Answer 4

oww i got 5.9
