Question

plzz tell me its urgent...its really urgent man!!​

Answer 1

Answer:

z+140°=180° (because, M is straight angle)

z=180°-140°=40°

y+100°=180° (because, TEM is straight angle)

y=180-100

y=80°

x+y+z=180° (sum of interior angles of triangle is 180)

x+80°+40°=180°

x+120=180

x=60°

hence, x=60°, y=80°and z=40°

Answer 2

Answer:

x = 60°

y= 80°and

z = 40°
