This type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
Answer:
8, 15, 17
Step-by-step explanation:
The 2nd option. You know this by using this math formula: a^2 + b^2 = c^2. That is the formula to find a right triangle. So if you square 8 and 15 you get 64 and 225, and if you add them together you get 289, which is 17^2. Hope this helps! :)
To solve this, simply multiply:
5 x 7 = 35
