An aerial photograph is taken of a building. the photograph is made when the angle of elevation of the sun is 25 degrees. the shadow is determined to be 80 feet long. how tall is the building?

  37.3 ft

Step-by-step explanation:

SOH CAH TOA reminds you that ...

  Tan = Opposite/Adjacent

In this geometry, the side adjacent to the angle is the 80 ft shadow, and the opposite side is the height of the building. Then we have ...

  tan(25°) = height/(80 ft)

  (80 ft)·tan(25°) = height ≈ 37.3 ft

based on context clues you gave i'm assuming the answer would be c.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
