**Question:**

Joe is driving along a road that takes a sharp right turn. At the vertex of the turn, it is met by another road. One of the angles between the roads is 40°. What is the other, complementary angle between these roads?

- 50°
- 40°
- 320°
- 140°

**Explanation:**

This question is about complementary angles. Complementary angles are two angles that add up to 90°. To find the complementary angle to 40°, subtract 40° from 90°. 

**Calculation:**

90° - 40° = 50°

Therefore, the other complementary angle is 50°.
