Question

An observer on the ground is x meters from the base of the launch pad of a rocket, which is at the same level as the observer. A few seconds after the rocket takes off vertically, the observer sees its tip at an angle of q° from the horizontal. How far above the ground is the tip of the rocket at that instant? Assume that the ground is level.

Answer 1

Here's a sketch of the situation. How would you start?

Answer 2

i would start by deciding whether to use sin cos or tan?

Answer 3

i kinda confused but i believe it would be x tan over q ?

Answer 4

\[tan(q)=\frac{h}{x}\] so\[h=x tan (q)\]

Answer 5

so the one i picked was right ?

Answer 6

thank you
