Question

what value of a and b make quadrilateral MNOP a parallelogram​

Answer 1

Answer:

if MNOP is a parallelogram

:.4a+b=21(opposite sides of parallelogram are equal)

:.3a-2b=13(opposite sides of parallelogram are equal)

:.a=(21-b)4

:.3(21-b)4 - 2b = 13

:.12*21 - 12b - 2b = 13

:.252-14b=13

:.-14b=13-252

:.14b=252-13

:.b=239/14=17.071approx

:.a=(21-17.071)4=3.929*4=15.716approx
