brainly.com/question/9480049The lengths of the sides of the triangle are 16, 63, and 65.
a0 = 63
a1 = 65
_____
You have
.. a0² +16² = a1²
You want
.. a1 = a0 +2
so
.. a0² +256 = (a0 +2)² = a0² +4a0 +4 . . . . substitute and expand
.. 252 = 4a0 . . . . . . . . . subtract a0² +4
.. 63 = a0 . . . . . . . . . . . .divide by 4
.. a1 = 63 +2 = 65
I think you just have to divide them
C is (half of B)².
in this case, B is 6, so C=3²=9
