A straight angle measures 180 degrees.

Angle x and the 150-degree angle form a straight angle.

x + 150 = 180

x = 30

Angle z and the 100-degree angle form a straight angle.

z + 100 = 180

z = 80

Now you know the measures of two angles of the three angles of the triangle. The sum of the measures of the angle of a triangle equals 180 degrees.

x + y + z = 180

30 + y + 80 = 180

y + 110 = 180

y = 70

Answer: x = 30; y = 70; z = 80
