A building casts a shadow that's 88 meters long on the ground. The straight line distance from the top of the building to the end of the building of the shadow creates is at a 32° angle with the ground. what is the approximate hight of the building (the answer is to be rounded to the nearest meter)

The triangle formed by the building, its shadow and the line between the end of shadow to top of the building has the following values:-

adjacent side = 88 m, angle of elevation = 32 degrees and we need to find the length of the opposite side (that is height of the building).

A = 88, m < elevation = 32 and O = ?

SOH-CAH-TOA - so we need the tan of 32:-

tan 32 = O / 88

O = 88 * tan 32 = 55m to nearest meter (answer)
