Answer:


x=86^(\circ)


y=94^(\circ)


z=54^(\circ)

Explanation:

First, let's look at the largest triangle (two smaller triangles are combined) to solve for
z. Since the sum of the angles in a triangle adds up to
180^(\circ), we can write the equation:


20+74+32+z=180


z=180-126


z=54^(\circ)

Looking at the smaller triangle on the left,
y (exterior angle) is the sum of the two opposite interior angles of the triangle on the left:


y=74+20


=94^(\circ)

Since
x is the exterior angle of the triangle on the right, it is equivalent to the sum of the opposite interior angles of that triangle:


x=32+z


=32+54


=86^(\circ)

Hope this helps :)
