Answer:
hope it helps uhh .. :)
Step-by-step explanation:
120 is on a straight line...(which we know that is 180)... *straight is 180 degree
if we subtract 120 from 180 we'll get the value of the 2nd interior angle
180 - 120
2nd angle = 60 (degree)
the sum of triangle's three interior angles are 180
80 + 60 + the third interior angle = 180
140 + the third interior angle = 180
the third interior angle = 180 - 140
the third interior angle = 40 (degree)
third angle is 40 degree
now 40 degree and the X is on straight line wich we know that is 180
subtract 40 from 180 to get the value of X
180 - 40
X = 140 degree
