The square of a whole number n lies between 80 and 150, so n lies between √80 and √150.
n is a whole number and lies between 8.9 and 12.2, so n can be 9, 10, 11, or 12.
The possible values for n are 9, 10, 11, and 12.

The slide and the ladder made a right angle triangle with the ground. The angle that the slide made with the ground is labeled as 
in the diagram below. We can use the trigonometry ratio to work out the size of the angle.
8.3 is the side opposite to the angle and 14.5 is the hypotenuse. We need to use the Sin ratio
