Question

find x and y
please tll ​

Answer 1

120° + y = 180° (Linear pair)

y = 60°

Let the three angles of the given triangle be x,y and z.

According to the figure,

100° + z = 180° (Linear pair)

z= 80°

We know,

Sum of all angles of a triangle = 180°

thus,

x + y + z = 180°

x + 60° + 80° = 180°

x = 180° - 140°

x = 40°

:)

Answer 2

y + 120 180 (coointerior angle)

y 180-120

y20

now

x100 (alternate angle)

therefore

x100

y20
