Question

Find the length of a leg

Answer 1

Identify the side you want to find.

You know that you are given an angle of 90 and 45, but this would mean that the other angle is 45 resorting in the legs having the same length.

Let's do this:


So we know that `16` is `the hypotenuse`.

And that `x` is the closest side meaning it is the `adjacent`.

This means you will use the cosine ratio.

CAH = cos(x) = \(\frac{opposite}{hypotenuse}\)

\(\large\bf{cos(45)=\frac{x}{16}}\)

\(\large\bf{16 \times cos(45) = x}\)

Answer 2

CAH = cos(x) = \(\frac{adjacent}{hypotenuse}\)*

Answer 3

so 720? Then you would need to square it right?

Answer 4

720?

How did you get that?

Answer 5

oof hold on I forgot to clear my calculator and I got something random

Answer 6

okie
