Question

Find each missing measure, measure of angle 1,2,3,4

Answer 1

1. 75°
2. 56°
3. 124°
4. 41°

Explanation:

∠1 is complementary to 15°, so is 90° -15° = 75°

∠2 completes the triangle with angles 49° and 75°, so is 180° -49° -75° = 56°

∠3 is supplementary to ∠2, so is 180° -56° = 124°

∠4 is complementary to 49°, so is 90° -49° = 41°
