Question

A 75${}^{\circ }$ angle can be made by drawing angle bisector between a 90${}^{\circ }$ angle arm and a ___ angle arm.

• A. 80${}^{\circ }$
• B. 70${}^{\circ }$
• C. 60${}^{\circ }$
• D. 50${}^{\circ }$

Answer 1

The correct option is C 60${}^{\circ }$

$75=\frac{90+60}{2}$

Hence, bisecting 90${}^{\circ }$ and 60${}^{\circ }$
will give 75${}^{\circ }$.
