Answer:

x=90 degrees

y=142 degrees

z=128 degrees

Step-by-step explanation:


Answer:

X = 95 degrees

Y = 147 degrees

Z = 128 degrees

Step-by-step explanation:

Angle z can be found as : [tex]180-52[/tex] = 128 degrees. This is because the sum of the internal angle and the external angle on the same vertex is 180°

The opposite of angle X can be found as [tex]180-(45+50)[/tex] = 85 degrees.

Now angle X lies on the same line. We can say X is exterior angles to the opposite interior angle of bigger triangle.

Angle X = [tex]180-85[/tex] = 95 degrees

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Angle Y = [tex]52+95[/tex] = 147 degrees.
