I believe it’s x=2.5 or x=2 1/2 or x=5/2
They are all the same answers in different forms . Hope it’s right

Answer:
B. m<B = 65°; m<C = 115°
Step-by-step explanation:
First find the value of x:
3n + 20 = 6n - 25 (opposite bangles if a parallelogram are equal)
Collect like terms
3n - 6n = -20 - 25
-3n = -45
Divide both sides by -3
n = 15
✔️Find angle B:
m<B = 3n + 20
Plug in the value of n
m<B = 3(15) + 20
m<B = 45 + 20
m<B = 65°
✔️Find angle C:
m<C = 180 - m<B (consecutive angles of a parallelogram are supplementary)
m<C = 180 - 65
m<C = 115°
