Question

In a parallelogram ABCD,∟A=3Y º and ∟C=(2Y+75 º).Find the value of Y.​

Answer 1

Answer:

Given

angle(A) = 3Y degree

angle(C) = (2Y+75) degree

In the parallelogram Opposite angles are equal .

So In parallelogram ABCD

angle(B) = angle(D)

and

angle(A) = angle(C)

3Y = 2Y+75

2Y - 2Y =75

Y = 75 degree
