Answer:
Explanation:
First, it is important to remember the definition of "Complementary angles".
Complementary angles are defined as those angles whose sum is 90 degrees.
In this case, let "x" represents the measure in degrees of the complementary angle to the given angle (which measures 45 degrees).
Based on the information given before, you can set up the following equation:
Therefore, you must solve for "x" in order to calculate the measure of that angle.
To do this, you can apply the Subtraction property of Equality subtracting 45° from both sides of the equation.
Through this procedure, you get the following result:
