Question

The hypotenuse of a right triangle is 17cm long if one of the remaining two sides is 8 cm in length. Find the length of the other side.​

Answer 1

Answer:

15 cm

Step-by-step explanation:

Let the other side be x.

Then, (x)^2+(8)^2=(17)^2 {Pythagoras Theorem}

Or, (x)^2=(17)^2-(8)^2

Or,x=√(17)^2-(8)^2

Or,x=√289-64

Or,x=√225

Or,x=15cm

Answer 2

Step-by-step explanation:

in a right angled triangle,

hypotenuse = 17cm

if one side id 8 cm,

let another side be x cm

so, by Pythagoras theorem

hypotenuse ² = base² + perpendicular ²

(17)² = (8)² + (x)²

289 = 64 + x²

or, x² = 289 - 64

x = √225

x = 15 cm

the length of the other side is 15 cm.
