Question

Find the degree measure of the angles in the given figure.​

Answer 1

Answer:

Points in the interior R, C, N, X

Points in the exterior T, U, Q, V, Y

Points on the arms of the angles A, W, G, B

Answer 2

Solution :

Here ,

•By linear pair , Sum of all angles is 180°

• ∠AOQ + ∠QOS + ∠SOB = 180°

=> z + 40° + z + 20° + z + 30° = 180°

=> 3z + 90° = 180°

=> 3z = 180° - 90°

=> z = 90°/3

=> z = 30°

• ∠AOQ = Z + 40° = 30°+40° = 70 °

• ∠QOS = z + 20° = 30° + 20 ° = 50°

• ∠ SOB = z +30° = 30° + 30° = 60°
