Question

P Q R is a straight line.
QRST is a parallelogram.

a.work out the value of x
b.workout the vaplue of Y
c.workout the value of Z​

Answer 1

Step-by-step explanation:

A. Since QRST is a parallelogram. So, QR is || to ST

Angle X = 73° (Using alt. interior angle)

B. Angle Y = 46° (Using alt. interior angles)

C. Angle Z = Angle T (opposite angles of a parallelogram is same)

so, angle Z = 73°

;-)

Answer 2

In parallelogram QRST;

y=46 (since alternative interior

angles)

Exterior angle PQT=Interior angle (QTS+QST)

x=73+46

x=119

x=z=119 (since corresponding angles)
