Vedmedyk [2.9K]

Answer:

$x= 80^o$

Step-by-step explanation:

Given

$\angle Z = 36^o$

$\angle WYZ = 100^o$

Required

Find x

$\angle WYZ$ and x are on a straight line.

So:

$\angle WYZ + x= 180^o$

Make x the subject

$x= 180^o -\angle WYZ$

Substitute known value

$x= 180^o -100^o$

$x= 80^o$
