Question

Two angles are complementary, as shown in the diagram below.
xº
15°
Part A: Use the definition of complementary angles to set up an equation that can be used to solve for the value of c.
Part B: Solve for the value of x. In your final answer, include all of your calculations.

Answer 1

Answer:

A; x + 15 = 90

B: x = 75

Step-by-step explanation:

A: complementary angles are angles that add up to 90 degrees. This means that x and 15, the two angles that are complementary, will add up to 90:

x + 15 = 90

B: For B, you just need to solve the equation for x:

1. x + 15 = 90

2. x = 75

Step 1 is the given equation

In step 2, 15 was subtracted from both sides
