Answer 1

Answer:

15

Step-by-step explanation:

As we know that opposite angles are equal in parallelogram

Thus,

(8x+20)° = (10x-10)°

20+10 = 10x-8x

30 = 2x

x = 30/2

x = 15

Answer 2

Answer:

x=15°

∠Q=40°

Step-by-step explanation:

∠P=∠R

∵opposite angles in a parallelogram are equal

∴8x+20=10x-10

⇒-2x=-30

⇒x=15°

∴ ∠R =10x-10

=10*15-10

=140°

∠Q+∠R=180°

∵consecutive angles are supplementary

⇒∠Q=180-140

∴ ∠Q=40°
