Could someone please check my work? I was assigned multiples of 3...so there arent very many..I also skipped a few that I did not understand...
In all of your problems you are dealing with a specific kind of right triangle: one where the two legs are equal. So
<-- Since y = x
If you are given one of the legs, you know the other one is equal to the given leg. If you are looking then for z then solve the above equation for z.
If you are given z then you know the two legs are equal and equal to x in the above equation. So solve it for x.
Example: You are given y = 5. Thus x = y = 5. And
.
Example: You are given z = 20. Thus
(Which simplifies to .)
Doing the other kinds of triangles involves a similar process, though, of course, x and y may not be equal. Either way we still have and you can work from there.

Hello, aikenfan!
You did quite good . . . the ones you skipped are rather tricky.
For 1 - 10:Code:* * * *45°* z * * * * y * * * 45° * * * * * * * * * x
For the 45-45-90 triangle, think of the sides as: .
So, if we know one side, we can find the others.
In #3, we are given:
Then: .
In #6, we are given:
Divide both sides by
Rationalize: .
Therefore: .
In #9, we are given: .
Divide both sides by
. .

Try the same technique on the other problems.
For the 30-60-90 triangle, think of them as: .
