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

Answer:

third side = 15 cm

Step-by-step explanation:

• let the 3rd side be x
• right angle traingle

FORMULA:

(hypotenuse)² = (opposite side)² + (adjacent side)²

${(17)}^{2} = {(8)}^{2} + ( {x)}^{2} \\ 289 = 64 + {x}^{2} \\ 289 - 64 = {x}^{2} \\ 225 = {x}^{2} \\ x = \sqrt{225} \\ x = 15$

• 3rd side = 15 cm
