Question

the top angle of the triangle is a right angle. the question is find the missing lengths of the sides. can someone please answer this for me

Answer 1

Answer:

a

Step-by-step explanation:

if the top angle is 90° then the traingle is an isosceles triangle.

meaning that a=b.

this specific traingle is a silver traingle meaning that the ratio of the sides is 1:1:the root of 2.

so if

$9 \sqrt{2}$

is 'a' multiplied by the root of two we need to divise it by the root of two to get 'a' and a=b.
