Question

Quadrilateral QRST is a parallelogram. Determine the measure of QRS

Answer 1

x=9

Explanation:

In a parallelogram, opposite angles are equal.

So that means

2(3x - 4) = x + 37

6x - 8 = x + 37

5x = 45

x = 9

Answer 2

x+37=2(3x-4) opposite angle of the parallelogram are equal

x+37=6x-8

37+8=6x-x

45=5x

x=9

the measure of QRS=2(3×9-4)=46
