Question

Find angle x in each figure.​

Answer 1

Answer:

x=360-(90+90+60)

x= 360-240=120

Answer 2

A Quadrilateral

let angles be as ABCD

so∠A=60°

∠B=right angle=90°

∠C=x°

∠D=right angle=90°

∴∠A+∠B+∠C+∠D=360°(sum of all angles of quadrilateral is 360°)

∵60°+90°+x°+90 °=360°

=240 °+x°=360°

x°=360°-240°

= 120°
