Question

in figure, if AB || CD then find the value of x

Answer 1

DQP and EPB are supplementry angles

Therefore,

2X - 10 + 5X - 20 = 180

7X = 210

X = 30

Have a nice day :)

Answer 2

Given:
{RGB}
AB||CD

$<marquee>So angle DFQ and BPQ will be supplementary</marquee>$

So ,5x-20+2x-10=180

=>7x-30=180

=>7x=180+30

=>x=210

=>x=210/7

=>X=30

So, the value of X is$<b>30</b>$
