Question

Copy the diagram and calculate the sizes of x°, yº and zº. What is the sum of the angles of the

triangle?
​

Answer 1

180

Explanation:

to find angle :

x =180 - 150=30

y =180-80=100

z = 180-130=50

so, 30+50+100=180

Answer 2

Angle x = 30 degrees
Angle y= 100 degrees
Angle z = 50 degrees
Sum of the angles = 180 degrees
