Question

In a parallelogram Abcd, angle A =(2x+10) and angle C=(3x-20).find the value of x

Answer 1

Answer:    In a parallelogram , opposite angles are equal. <A=<C

Step-by-step explanation:  In paralellogram ABCD, <A=<C

Given,   <A=2x+10     ,   <B= 3x-20

<A=<C

2x+10 = 3x-20

2x-3x=-20-10

-x=-30

x=30

hope it hlpd you!!!
