You are flying a kite that has been released with 200 m of string. The string forms an angle of 30° with the ground. How high is the kite flying?

Use the fact that sin(30) = height/200

 

$${\mathtt{height}} = {\mathtt{200}}{\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{30}}^\circ\right)} \Rightarrow {\mathtt{height}} = {\mathtt{100}}$$

 

height = 100 m
