Question

in an isosceles triangle the measure of one angle is 90 and base= altitude= x c.m find the length of the hypotenuse

Answer 1

one angle is 90 means that it is a right angle triangle.
using Pythagoras theorum,,

let the hypotenuse be a

hypotenuse^2=alt^2+base^2
(a)^2=x^2+x^2
a^2=2x^2
a=√2x^2
a=x√2 cm.

hope this will help u
