When the base and the height of a triangle are the same. the hypotenuse is that number times sqrt2.
B and C are 7, so a would also be 7
First, you would create an equation for this problem.

=

Next, you would cross multiply.
15x = 1,800
Now, you would isolate the x. To do this, you would divide both sides by 15.
x =
120It is a 120% increase. I hope this helps!
