Identify Given Information: Identify the given information and what is being asked.Angle TSR is the unknown we need to find.
Recall Complementary Angles Definition: Recall the definition of complementary angles. Complementary angles add up to 90 degrees.
Set Up Equation: Use the given information to set up an equation.If the measure of an angle is 30 degrees, its complementary angle is 90 degrees minus the measure of the angle.
Perform Subtraction: Perform the subtraction to find the measure of the complementary angle. 90∘−30∘=60∘.
Realize Mistake: Realize a mistake was made; the problem asks for the value of angle TSR, not its complementary angle.We do not have enough information to solve for angle TSR.
