Find the length of the third side of the right triangle

b = 15

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

17² = 8² + b² , that is

289 = 64 + b² ( subtract 64 from both sides )

225 = b² ( take the square root of both sides ), thus

b = = 15

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
