Answer:
x=131 degree
Explanation:
sum of angles in a straight line=180 degree
one angle=49 degree,
second angle=x
hence,x+49=180
x=180-49
x = 131
The angles x and 49 form a straight angle whose sum is 180°
Equate the sum of the 2 angles to 180 and solve for x
x + 49 = 180 ( subtract 49 from both sides )
