A kite is 30m from the ground. A cyclist observes it flying when he looks up at an angle of 20°. After 15 seconds, the cyclist has to look up at an angle of 60° to see the kite. Calculate the speed of the cyclist. Give your answer in km/h.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
