Answer»

Answer:

x =115

y =115

Step-by-step explanation:

in figure SUPPOSE a ANGLE in both SIDES in interior SIDE z

sum ofall angles of triangle is 180

50+z+z=180

50+2z=180.

2z=180.-50 =130.

z=130/2 = 65

so y+z=180.(linear pair)

y+65=180.

y= 115

x + z = 180.(linear pair)

x+65=180 =115
