Use your trig ratios to find the missing sides.
Add all the sides up and you have your perimeter!

<em>*notice how one of the 10 is left out because it is inside the shape so we can't use that to find perimeter.</em>
Let 'x' be the problems worth 2 points.
Let 'y' be the problems worth 3 points.
Since, there are 38 total problems.
So, (equation 1)
x = 38-y
Since, a perfect score is 100 points.
So, (equation 2)
Substituting the value of 'x', we get
y = 24
x+y = 38
x = 38-24 = 14
So, 14 problems are worth 2 points and 24 problems are worth 3 points.
