Answer:
60 units^2
Explanation:
In order to find the area of a triangle, you do baseXheight/2. However, we don't have the height. So, we use the pythagorean theorem to solve for the missing side.
8^2+x^2=17^2
64+x^2=289
x^2=225
x=15
So, now we can solve for the area.
15*8=120
And divide by 2 we get 60
