Question

I really need help plzzzzzzz

Answer 1

Answer:

For Question 1

$\angle Z =72$°

For Question 2

$\angle Y =130$°

Step-by-step explanation:

Given

$\angle X =108$°

$\angle W =50$°

For a Quadrilateral inscribed in a circle we have opposite angles are Supplementary that is

For question 1

$\angle X + \angle Z = 180\\108 + \angle Z =180\\\angle Z =180-108=72$

For question 2

$\angle W + \angle Y = 180\\50 + \angle Y =180\\\angle Y =180-50=130$
