Math Problem Statement
The measure of one angle is six more than half the measure of another angle. If the angles are complementary, find both measures.
Solution
To solve this, let’s define the angles.
Let:
- be the measure of the first angle.
- be the measure of the second angle.
Step 1: Set up the equations
We know two things:
- The angles are complementary, meaning their sum is . This gives us the equation:
- The measure of one angle is six more than half the measure of the other angle. So, we also know:
Step 2: Solve the system of equations
We have two equations:
Substitute the second equation into the first: Now, solve for .
Step 3: Solve for
Combine like terms: Subtract 6 from both sides: Multiply both sides by to isolate :
Step 4: Solve for
Now that we know , substitute this back into the equation for :
Final Answer
The two angles are:
These angles are complementary since .
