a = 1%2F2bh = highlight_green%28%281%2F2%29%283%28x-5%29%29+=+%283%2F2%29%28x-5%29%29
...
6+=+%283%2F2%29%28x-5%29
...
6+=+%283%2F2%29x+-+%283%2F2%29%285%29
...
Multiply the entire equation by 2
12 = 3x - 15
12 + 15 = 3x/
27 = 3x
highlight_green%28x=9%29
...
3^2 + (9-5)^2 = c^2
9 + 16 = c^2
25 = c^2
sqrt%2825%29+=+sqrt%28c%5E2%29
highlight_green%28c=5%29
