What is the measure of the angle that the ladder makes with the wall?

30°

Step-by-step explanation:

The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)

Measure of angle the ladder makes with the ground = 180 - 120 = 60°

Therefore,

The measure of angle the ladder makes with the wall = 180 - (60 + 90°)

= 30°
