Answer 2

Answer:

The Correct Answer is Option (a): 20 Degrees

Step-by-step explanation:

The total of the angles in a linear pair is always 180 degrees. Supplementary angles are another name for these types of angles. Angles with a same vertex are called neighboring angles.

Since POQ is a straight line,

40 + 4x + 3x = 180

40 + 7x = 180

7x = 140

x = 20
