math regarding trigonometry

Question

A car drives east for 31 miles and then north for 84 miles.

What is the bearing from the starting point to the car's current position?

Select N or S in the first pull down menu and E or W in the second pull down menu. Round your angle to one decimal place. Do not enter a degree symbol.

Answer 1

Draw and label a diagram!

A is the starting point

B is the turning point (90°)

C is the ending point

tan CAB = 84 / 31

tan CAB ≈ 2.71

m∠CAB ≈ 69.74°

Bearing equals 90° - 69.74°
