The correct Answer is:
To solve the problem of finding two complementary angles that differ by \(14^\circ\), we can follow these steps: ### Step 1: Define the angles Let one angle be \(x\). Since the angles are complementary, the other angle will be \(90^\circ - x\). ### Step 2: Set up the equation According to the problem, the difference between the two angles is \(14^\circ\). Therefore, we can write the equation: \[ x - (90^\circ - x) = 14^\circ \] ### Step 3: Simplify the equation Now, simplify the equation: \[ x - 90^\circ + x = 14^\circ \] \[ 2x - 90^\circ = 14^\circ \] ### Step 4: Solve for \(x\) Add \(90^\circ\) to both sides: \[ 2x = 14^\circ + 90^\circ \] \[ 2x = 104^\circ \] Now, divide by \(2\): \[ x = \frac{104^\circ}{2} = 52^\circ \] ### Step 5: Find the second angle Now, substitute \(x\) back to find the second angle: \[ 90^\circ - x = 90^\circ - 52^\circ = 38^\circ \] ### Conclusion The two complementary angles are \(52^\circ\) and \(38^\circ\). ---
