Question

in this fig find x and y.​

Answer 1

angle y + 70°+ 50°= 180° {Angles on straight line}

angle y=180-120=>60°

***angle y = 60°

angle x= 180°-(y+50)

=>180°-110=> 70°

***angle x= 70°

Answer:

hope it helps...

Answer 2

<1 = 50° (beacuse Ac is transversal of l and BC )

We know that

Liner pair =180°

70° + <1 + y = 180°

70°+50°+y=180°

y=60°

Sum of all angles of triangle= 180°

60°+50°+x=180°

x= 70°
