Answer:
y + z = 40 (alternate opp. angles)...eq 1
x + z = 50 (alternate opp. angles)...eq 2
x + y + z = 180...eq 3
from eq 1 : z = 40- y
put in eq 2 : x + 40 - y = 50
x - y = 10
now x= 10+y
put the values of x and z in eq 3
10+y +40- y +y = 180
50 + y = 180
180 - 50 = y = 30
put the value of y in eq 1 for getting value of z
30 + z = 40
z = 10
similarly in eq 2 put the value of z for finding the value of x
x + 10 = 50
x = 40
mark me brainlist plzz..
