Question

The hypotenuse of a right triangle is,17 cm long if one of the remaining side is of 8 cm long.find the length of 3 side

Answer 1

h²=p²+b²
(17)²=(8)²+(b) ²
289=64+b²
b²=225
b=15 cm

Answer 2

${(p)}^{2} + {(b)}^{2} = {(h)}^{2} \\ \\ {(8)}^{2} + {(b)}^{2} = {(17)}^{2} \\ \\ 64 + {b }^{2} = 289 \\ \\ {b}^{2} = 289 - 64 \\ \\ {b }^{2} = 225 \\ \\ b = \sqrt{225} \\ \\ b = 15$
Third side = 15cm
