Question

solve the following:
​

Answer 1

Answer:

supplementary angle =180°

and the triangle =180°

but each angle should be equal to 60°

therefore x=60°

y=60°

Answer 2

x= y=60

Step-by-step explanation:

y+1 + x =180

120+1 = 180(linear pair)

1= 60

1=y(angle opposite to equal side equal)

y=60

x+y+1=180

60+60+x=180

x=180-120

x=60
