Question

One of the angles of a triangle is 90˚. The length of two sides containing the right angle are 15cm and 8cm. what is the length of the side opposite to the right angle?​

Answer 1

base= 8cm

height =15cm

hypotenuse=?

let hypotenuse be x

By Pythagoras theorem

${hyp}^{2 } = {base}^{2} + {alt}^{2} \\ {x}^{2} = {8}^{2} + {15 }^{2} \\ 64 + 225 \\ {x}^{2} = \sqrt{289} \\ x = 17$
