Question

What is the length of leg s of the triangle below?

Answer 1

B because in a 45-45-90 triangle, the leg lengths are the same (isosceles).

Answer 2

Answer:

Length of leg s is 3 units.

Step-by-step explanation:

Given the 45-45-90 triangle, in which length of hypotenuse is $\sqrt{18}$ and one leg is 3 units.

we have to find the length of other leg i.e leg s

As two angles of triangle are equal implies given triangle is isosceles.

As the two sides of isosceles triangle are equal.

Hence, the length of leg s must be equal to the length of other leg which is given 3 units.

Hence, length of leg s is 3 units.
