Someone help me please
45-45-90 triangles

Answer:
Side AB = [tex]9\sqrt{2}[/tex]
Side AB = [tex]9\sqrt{2}[/tex]
Side CB = 36
Step-by-step explanation:
This is a special right triangle and it's also an isosceles triangle
therefore the measure of AC = AB and they are both = [tex]9\sqrt{2}[/tex]
for this special triangle the measure of hypotenuse (CB in here) is represented with [tex]x\sqrt{2}[/tex] and the legs are represented with x, each
since legs' lengths are given as = [tex]9\sqrt{2}[/tex] then x = [tex]9\sqrt{2}[/tex]
replace the x in front of [tex]x\sqrt{2}[/tex] with [tex]9\sqrt{2}[/tex]
[tex]9\sqrt{2}[/tex] * [tex]\sqrt{2}[/tex] = 36
