Question 1152142


if the angle of elevation of the sun is {{{29}}} degrees, and the shadow is {{{70}}} feet long, how tall is the​ building?

{{{tan(29) = h/70}}} Now you multiply both sides by {{{70}}} to get:
{{{70*tan(29) = h}}} You can do this in your calculator.
{{{h = 38.8016336}}} Round the the nearest integer:
{{{h = 39}}} feet.
