Question

Find the value of x and y that will make each quadrilateral a parallelogram.​

Answer 1

3y+3y=180°{sum of opposite angle of parallelogram are supplementary}

6y=80

y=180/6

y=30°

again,

4y-65+x=180°{ sum of of opposite angle of parallelogram are supplementary }

4×30-65+x=108

x=180-55

x=125

so to make quadrilateral as parellogram

• 3y=3y
• 3×30=3×30
• 90°=90°

Answer 2

the opposite Angles sum up to give 180

Explanation:

3y +3y = 180

y=30

if y = 30 the x = 55

are you clear?
