Answer 2

Answer:

FIB ANSWERS: 55°, 55°, 125°

Step-by-step explanation:

Since it is a straight line and there are two adjacent angles

Therefore, the sum of angles = 180° (angles in a linear pair)

Now x + (3x -40) = 180°

4x - 40 = 180°

4x = 180 + 40

x = 220 / 4

therefore x = 55°........

FIB

Ans1 : x= 55, Ans2: 55 , Ans3 = 3x-40 = 165-40 = 125°
