Question

Please help? what does x equal?

Answer 1

Explanation:

Sum of all angles in a trapezium equals 360° and we two 90° angles so now,

`90+90+x+(x-60)=360\\180+2x-60=360\\2x=360-180+60\\2x=180+60\\2x=240\\x=240/2\\x=120`

so now the angles are 90°,90°,120° and 60° i also attached an image so you can understand better.
