Question

what is the answer?​

Answer 1

HEY -:)

w=80°

x=60°

y=100°

z=120°

☺☺☺☺☺☺☺

Answer 2

x=180°-120°=60°

y=180°-80°=100°

z=180°-60°=120°

w=?

To find w we must first calculate the linear pair of w.(w')

Since the figure is a quadrilateral.

Ans since; The sum of all angles inside the quadrilater is 360°.

So;

By angle sum property of a quadrilateral;

60°+80°+120°+ w' = 360°

=> 260° + w' =360°

=> w' =360°-260°=100°

So w= 180°-100°=80°

Hence;

x+y+z+w=60°+100°+120°+80°=260°

Hope it helps...
