Question

Please help me to solve this mathematics question ​

Answer 1

Answer:

60+60+y=180

y=60

x=y=z=60

Answer 2

Answer:

x+120=180(being supplementary angle)

x = 180 - 120

x = 60

x + x + y = 180 ( the sum of triangle is 180 )

2x + y = 180

2*60 + y = 180

y = 180 - 120

y = 60

it is isosceles triangle because  it has two side equal or angle equal
