Question

For which of the following pair of angles, horizontal range is same ?

• A. $30^{\circ }$, $45^{\circ }$
• B. $40^{\circ }$, $50^{\circ }$
• C. $30^{\circ }$, $50^{\circ }$
• D. $30^{\circ }$, $40^{\circ }$

Answer 1

Answer: (B)

Horizontal range is same for complementary angles i.e., $\theta$ and $90^{\circ }-\theta$ Hence, horizontal range is same for $40^{\circ }$ and $50^{\circ }$, i.e. $\left(90^{\circ }-40^{\circ }\right)$
