So, we have SAS.
And we want to find the side opposite to the angle.
Therefore, we can use the Law of Cosines:
Again, it is important what we substitute.
a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.
C is our angle. So, substitute 64 for C.
And c is what we’re trying to solve.
Therefore:
Simplify:
Add:
Take the square root of both sides:
Use a calculator. So, c is approximately:
The c is our y. So, y is approximately 11.9 units.
