Question

Find the measure of x and y in the
following figures.
Answer pls dena
​

Answer 1

Answer:

a) angle B = 72°

exterior angle at C = 105 °

therefore, interior angle at C = 180° - 105° = 75°

therefore X angle = 180° - ( 72° + 75°)

= 180° - 147° = 33°

b) angle R = 65°

angle Q = 35°

therefore interior angle at P = 180° - (65° + 35°)

= 180° - 100° = 80°

therefore X angle = 180° - 80° = 100°

c) angle A = 60°

exterior angle at point C = 110°

therefore, interior angle at C = 180° - 110° = 70°

therefore X angle = 180° - (60° + 70°)

= 180° - 130° = 50°

d) angle Q = 70°

interior angle at R = 45°

therefore, angle Y = 180° - 45° = 135°

therefore, X angle = 180° - (70° + 45°)

= 180° - 115° = 65°
