Question

Someone help me please
45-45-90 triangles

Answer 1

Side AB =
`9√(2)`

Side AB =
`9√(2)`

Side CB = 36

Explanation:

This is a special right triangle and it's also an isosceles triangle

therefore the measure of AC = AB and they are both =
`9√(2)`

for this special triangle the measure of hypotenuse (CB in here) is represented with
`x√(2)` and the legs are represented with x, each

since legs' lengths are given as =
`9√(2)` then x =
`9√(2)`

replace the x in front of
`x√(2)` with
`9√(2)`

`9√(2)` *
`√(2)` = 36
