In this unit, you've learned about trigonometry and its applications to right triangles and real-world scenarios that can be modeled
with right triangles. In such scenarios, sometimes we refer to an angle of elevation or depression. Both types of angles have one side
that is horizontal. From this side, the angle may open up (angle of elevation) or open down (angle of depression). These images show
the difference between the two.

In this task, you'll apply what you've learned to answer questions about a skateboard ramp that you and your friends are building for
your community skate park. The ramp will lead up to a platform. You'll be using a piece of wood that's 3.5 meters long for the ramp,
and the ramp's angle of elevation will be 28°. Use this figure as a model to answer the questions that follow.

Variation are of 2 types: Direct variation that states 'if x increases, y increases'. And inverse variation which states ' if x increases, y decreases and y increases x increases'.
1. The amount of fuel used on a trip increases as the size of the car increases and as the distance traveled increases. = Direct variation
2. As the number of people helping mow a lawn increases, the time it takes to mow the lawn decreases = Inverse variation
3. The cost of having a house painted increases as the size of the house increases. = Direct variation
Bianca's bank offers a savings account with a 2.1% APR,
compounded monthly. The the actual annual percentage yield on this account can
be calculated using i = (1+ r/m)^m, where i is the actual APR, r is the nominal
interest rate and m the compounding period in a year. APR is equal to 2.12%
Similar triangles can be extremely useful in architecture. For example, similar triangles can help represent doors and how far they swing. Also when using shadows that make the triangles you can use them to find the height of an actual object they can be used to construct many architectural designs and monuments for e.g, bridges. You can also determine values that you can’t directly measure. For e.g you. Can measure the length of your shadow and a tree’s shadow on a sunny day.
