Question

PQRS is a parallelogram. If st=3x-15 and qr=2x+10 what is st?

Answer 1

Answer:

st = qr (opposite side of parallelogram are equal)

3x-15 = 2x+10

3x-2x = 10+15

x = 25 ans

Answer 2

Step-by-step explanation:

In parallelogram adjacent angle are supplementary.

∴∠R+∠S=180

⇒3x+15+2x+5=180

⇒5x=160

⇒x=32

Option A is correct.
