Find the length of the third side of the right triangle

15

Step-by-step explanation:

Using Pythagorean theorem

17^2 = b^2 + 8^2

17 x 17 = b^2 + 8 x 8

289 = b^2 + 64

Subtract 64 from both sides

289 - 64 = b^2 + 64 - 64

225 = b^2

b^2 = 225

b = square root of 225

b = 15

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
