we know that

In a parallelogram consecutive angles are supplementary

In this problem

Angle Q and Angle R are consecutive angles

$(6x)\°+(20+2x)\°=180\°$

Solve for x

$8x=180-20$

$8x=160$

$x=20\°$

therefore

the answer is the option C

$x=20\°$

mestny [16]

f) 16 - p = 12 minus 12
4 - p = 0 plus p
p = 4
g) 18 - 2p = 6 divide by -2
-9 + p = -3 plus 9
p = 6
h) p x 2 + 4 = 9 divided by 2
p + 2 = 4.5 minus 2
p = 2.5
i) p x 4 - 3 = 1 plus 3
p x 4 = 4 divided by 4
p = 1
