Question

Please i need help :(

Answer 1

< 3 = 90°, < 8 = 43° and < 4 = 146°

Explanation:

Since < 1 and < 3 are on the same straight line, < 3 = 180° - 90°.

Since < 6 = 137° and < 6 and < 8 are on the same straight line, < 8 = 180° - 137° = 43°.

Since < 2 = 34° and < 2 and < 4 are on the same straight line, < 4 = 180° - 34° = 146°.
