Find the values of x, y, and z. The diagram is not to scale.

first option

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , thus

x = 180° - (60 + 35)° = 180° - 95° = 85°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

z is an exterior angle of the triangle , thus

z = 60° + 35° = 95°

Using the sum of angles in a triangle, then

y = 180° - (95 + 20)° = 180° - 115° = 65°

Thus

x = 85°, y = 65°, z = 95°
