Step-by-step explanation:
We can set up a systems of equations to find the value of the third side.
Let's assume that is the length of both sides 1 and 2. Let's also assume that
is the length of the third side.
We know that , and looking at the first clue we can make the equation
.
We can substitute y into the equation .
So the length of the side that is the same as the second is 7.
Now we can plug this into the equation to find
.
Hope this helped!
