from the top of a building that is 56 m high ,the angle of depression of a truck on the road is 32 degree . haw far is the truck from the foot of the building ,to the nearest metre?

2 answers

tan(theta) = opposite/adjacent

angle of depression means angle below the horizontal, so draw a triangle

tan(32 degrees) = x / 56 meters

solve by multiplying tan(32 degrees) by 56 meters
IN DEGREE MODE NOT RADIAN
Tan A = h/d.
Tan32 = 56/d,
d =
