Question

find x in the figure​

Answer 1

It's a Pentagon

Sum of all interior angles of a Pentagon is 540°

Angle D= 180-90= 90°{linear pair}

Angle E= 180-70=110°{Linear pair}

Angle C= 180-60= 120°{Linear pair}

Angle B= 90° {Given}

To find Angle A-:

540 - {90+110+120+90} [Angle sum

property]

540 - 410 = 130°

To find X -:

180-130°= 50 [Angle A and x are forming

Linear pair ,which are

supplementary]
