1.	Q.16Find the values of the unknowns in the following figures:25
Answer» y = 80° ( opposite angle are equal in parallelogram) z = 80° ( corresponding angle) x = 180° - 80° x = 100° ( adjacent angles) Next question angle 1 = 180° - 125° = 55° Similarly angle 2 = 55° angle a = angle 1 + angle 2 ( exterior angle theorem) angle a = 55° + 55° = 110°

Answer»

y = 80° ( opposite angle are equal in parallelogram)

z = 80° ( corresponding angle)

x = 180° - 80°

x = 100° ( adjacent angles)

Next question

angle 1 = 180° - 125° = 55°

Similarly angle 2 = 55°

angle a = angle 1 + angle 2 ( exterior angle theorem)

angle a = 55° + 55° = 110°
