The correct Answer is:
To solve the problem of finding two complementary angles that differ by 8 degrees, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Complementary Angles**: Complementary angles are two angles whose sum is 90 degrees. 2. **Assign Variables**: Let one angle be \( x \). Then, the other angle, being complementary, can be expressed as \( 90 - x \). 3. **Set Up the Equation**: According to the problem, the two angles differ by 8 degrees. This can be expressed as: \[ (90 - x) - x = 8 \] 4. **Simplify the Equation**: Simplifying the left side of the equation gives: \[ 90 - 2x = 8 \] 5. **Isolate the Variable**: To isolate \( x \), first subtract 90 from both sides: \[ -2x = 8 - 90 \] This simplifies to: \[ -2x = -82 \] 6. **Solve for \( x \)**: Divide both sides by -2: \[ x = \frac{82}{2} = 41 \] 7. **Find the Second Angle**: Now that we have \( x \), we can find the second angle: \[ 90 - x = 90 - 41 = 49 \] 8. **Conclusion**: The two complementary angles are \( 41^\circ \) and \( 49^\circ \). ### Final Answer: The two angles are \( 41^\circ \) and \( 49^\circ \).
