Question

Find the length of the third side of the right triangle

Answer 1

Answer:

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

Answer 2

Answer:

9

Step-by-step explanation:

        2       2

b + 8   = 17

b + 16 = 34

34 - 16 = 18

18 ÷ 2 = 9
