This is when you need to graph slope. This is useful because it helps you determine the x and y axis.
There are special properties to certain right triangles.
A 3-4-5 triangle will always be a right triangle. 9 divides into 3, and 15 divides into 5, so you can use ratios to find b.
Since 9 divides into 3, we will use this to set up proportions for the missing value:

Cross multiply the fractions.

Divide both sides by 3.

The missing value is
12.
