Question

Work out the size of each of the angles. thank you!

Answer 1

Explanation:

a=360°-300°=60°{reflex angle}

b=180°-40°=140°{straight angle}

hope it helps.

Answer 2

Explanation:

For a

a + 300° = 360° { being complete turn }

a = 360° - 300°

a = 60°

For b

b + 40° = 180° { being linear pair }

b = 180° - 40°

b = 140°
