To find the value of x, we know that the sum of the two complementary angles is 90 degrees.
One angle is 25 degrees, so the other angle can be represented as 5x degrees.
25 + 5x = 90
To solve for x, we can subtract 25 from both sides of the equation:
5x = 65
Finally, we can divide both sides of the equation by 5 to solve for x:
x = 13
Therefore, the value of x is 13.
