Answer:
Explanation:
We are given with a right angle.
A right angle is equal to 90° and the shape of right angle is the letter 'L'.
Here the right angle is divided into two angles i.e 5x and 55. So the sum of 5x and 55 will be 90.
5x + 55 = 90
Subtract 55 from both sides,
5x + 55 - 55 = 90 - 55
5x = 35
Divide both sides by 5,
x = 7
Henceforth the value of x is 7
Option (C) is the required answer.
