Question

find the values of the unknown ‘x’ and ‘y’in .the following diagrams​

Answer 1

Answer:

wait do you study on math book D1

Step-by-step explanation:

Answer 2

Answer:

ii) exterior angle = 80°

angle RST = 50°

angle y = exterior angle - angle RST

since exterior angle property( exterior angle = sum of two interior angles on the opposite side )

therefore y = 80°- 50° = 30°

x = 180° - (30° + 50 °) (angle sum property of triangle )

x = 180 - 80

x = 100°

v)exterior angle = 90°

x° + x° = 90

since exterior angle property (exterior angle = sum of two interior angles on the opposite side)

Therefore x = 90 ÷ 2 = 45°

y = 180° - (45° + 45° ) (angle sum property of triangle)

y = 180 - 90

y = 90°
