Question

If two complementary angles are equal, then what is the measure of each angle?

• A. ${30}^{\circ }$
  
• B. ${45}^{\circ }$
  
• C. ${60}^{\circ }$
  
• D. ${90}^{\circ }$
  

Answer 1

The correct option is B

${45}^{\circ }$

If two complementary angles are equal, then the measure of each angle is ${45}^{\circ }$
Sum of two complementary angles $={90}^{\circ }$
If both angles are equal then $\frac{90}{2}={45}^{\circ }$
