Find values of x and y for which ABCD must be a parallelogram. The diagram is not drawn to scale.
Arturiano [62]
ANSWER
x=4, y=8

EXPLANATION

If ABCD is a parallelogram, then

line AB is parallel to line DC .

This means that,

(x + 2) \degree
and

(2x - 2) \degree
are alternating angles.

Alternate angles are congruent.

This implies that,

2x - 2 = x + 2

We group like terms to obtain,

2x - x = 2 + 2

This simplifies to,

x = 4

Also, if ABCD is a parallelogram then,

BC is parallel to AD. This means that,

5y - 8 = y + 24

We group like terms to get,

5y - y = 24 + 8

This simplifies to,

4y = 32

We divide both side by 4 to get,

y = 8
