Respuesta :

z°=48°


Think about the rule that ALL triangles must have a sum of all angles to be 180°.

So 90°+42°=132°
180°-132°=48°

Feel free to check your work too!

90°+42°+48°=180°

So you’re answer is z°=48°

It’s 48º

You add 90 and 42 together to get 132. You then subtract 180 from 132 to get 48.
