Question

plsssssssssssssssssssssssssssssssssss answer this

Answer 1

To Find:-

• The value of x , y and z

Given:-

• Exterior angle of ∠B = 70°
• ∠A = 40°

Solution:-

step-by-step explanation:

• The value of x is

We know that in a parallelogram

( i ) opposite angles are equal.

180 - ∠B exterior angle = ∠B interior angle

⟹ 180° - 70°

⟹ 110°

So,

∠B interior angle = x ( opposite angles are equal)

x = 110°

• The value of y is

∠A = ∠x = 40° ( alternate angles )

• The value of z is

∠A = ∠B exterior angle ( alternate angles )

So,

⟹ 40° + z = 70°

⟹ z = 70° - 40°

⟹ z = 30°

Required Answer:-

• The value of x = 110°
• The value of y = 40°
• The value of z = 30°

Answer 2

Answer:

x = 110

y = 40

z= 30
