With these questions, the best approach is to draw a diagram to represent the question. Draw a right angle triangle with an angle of elevation 29 degrees (make sure to label the angle that meets the base and hypotenuse as 29 degrees).
From here, we say that the hypotenuse is the slide itself, which is 5.4 metres. Using basic trigonometric ratios, we can deduce that:
sin(29) = x/5.4
x = 5.4sin(29) which is approximately 2.62 metres.

Answer:
60 males in the aquarium
Step-by-step explanation:
It is a ratio problem. The ratio of female goldfish to male goldrish is 6:10. If you divide 216 (females) by 6 (females), you get 36. If you multiply 10 times 6, you get 60. So, the ratio turns into 216: 60. So, there are 60 males in the aquarium.
