Question

In a parallelogram ABCD, angle A= 3yº, angleB =(2y-5) and angle C= ( 3x + 3)". Find the value of x
and y.
​

Answer 1

Answer:

Two adjacent internal angles of a parallelogram are supplementary,

Therefore

∠A + ∠B = 180°

(3y) + (2y-5) = 180

3y + 2y - 5 = 180

5y - 5 = 180

5y = 185

y = 37

Opposite internal angles of a parallelogram have equal measure.

Therefore,

∠A = ∠C

3y = 3x + 3

3(37) = 3x + 3

111 = 3x + 3

108 = 3x

36 = x

Answer 2

this is the answer of that question.
