Question

State AC in simplest radical form (please help)

Answer 1

Here, triangle ABC is a right triangle with AB = AC. It mens its a 45-45-90 special triangle .

So we need to use the formula that determines the relationship between legs and hypotenuse and the formula is

$Hypotenuse = leg * \sqrt 2$

In the given diagram, leg = 12, so hypotenuse AC

$AC = 12 \sqrt 2$
