Answer :

62+95=157
180-157=23
z=23
I am solving this by assuming you are talking about a triangle.

Assuming your shape is a triangle:

First of all, a triangle's 3 angles ALWAYS add up to 180°. So by taking that into consideration:

180° - (62° + 95°)= 180° - 157°
                         = 23°

So angle Z would be equal to 23°.

Hope this helps!
