Question

The angle shows 5x and 25

it is a right angle
and complementary angle

Solve for the value of x

A. 50

B. 10

C. 13

D. 65

Answer 1

If the angle is complementary, then the sum of the angle and its complement is 90 degrees.

Therefore, we can write the equation:

5x + 25 = 90

Subtract 25 from both sides:
5x = 90 - 25
5x = 65

Divide both sides by 5:
x = 65/5
x = 13

So the value of x is 13.

The answer is C. 13.
