Question

In a parallelogram ABCD,if (3x-10)degree=angle B and (2x+10)degree =angle C , then find the value of x.

Answer 1

In a llgm(parallelogram) opposite angles are equal.
so,angle A=angleC
angle B=angleD
now,
3x-10+2x+10+3x-10+2x+10=360(quadrilateral
angles sum property.)
3x+2x+3x+2x=360
10x=360
X=360/10
x=36
