Question

find the value of z ​

Answer 1

Answer:

• Value of z is 80°

Step-by-step explanation:

First of all we have to find the value of all interior angles.

Value of x= 70° [alternate angles are always equal]

Value of y:

For finding the value of y first we have to find the value of ∠PRQ

∠PRQ= 180°-100°

= 80°

∴ Value of y= 180°-(∠PRQ+x) [Sum of angle of a triangle is 180°]

= 180°-(80°+70°)

= 180°-150°

= 30°

∴ Value of z= 180°-(70°+y)

= 180°-(70°+30°)

= 180°-100°

= 80°
