Find the value of x.

(x + 4)
147°

Step-by-step explanation:

From the question the angles lie on a straight line which means that the sum of their angles add up to 180°

Since angles on a straight line add up to 180°

To find the value of x add up all the angles and equate it to 180 to find x

That's

x + 4 + 147 = 180

x + 151 = 180

x = 180 - 151

We have the final answer as
