Answer:
x = 95 , y = 147 , z = 128
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the two opposite interior angles.
x is an exterior angle of the triangle , then
x = 45 + 50 = 95
vertex of triangle ( with x in it ) = 180 - 95 - 52 = 180 - 147 = 33
the vertex and y are adjacent angles on a straight line and sum to 180 , then
y = 180 - 33 = 147
z is an exterior angle of the triangle , then
z = 95 + 33 = 128
