Question

The measures of two adjacent angles on a straight line are x and (3x-40) degrees. Find x

Answer 1

Answer:

125°

Step-by-step explanation:

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

Now x + (3x -40) = 180°  

4x - 40 = 180°  

4x = 180 + 40  

x = 220 / 4  

x = 55°  

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