Question

In isosceles triangle find x and y angles where angle z is 30 degrees

Answer 1

Answer:

x=y=75

Step-by-step explanation:

z=30

in isoscales triangle

x=y (two sides with congruent angles)

so x+y+z=180

2x=180-30.....(x=y and z=30

2x=150

x=y=75

Answer 2

According to the Angle Sum Property of a Triangle,

x+y+z=180°

x+x+30°=180° (Isosceles Triangle)

2x+30°=180°

2x=180°-50°

2x=150°

x=150°/2

x=75°

x=y=75°
