Basically I just have to find x.

1. A rt triangle with hypotenuse 2x, and legs x and 5 radical 3 (the 3s under the radical). The equation should be xsquared + (5 radical 3) squared = 2xsquared and the answer is x = 5.

2. A rect has length 2.4 and width 1.8. I have to find the diagonal. I set the equation up as xsquared = 2.4squared + 1.8squared. The answer is 3.

What I would like is if someone could show the exact steps for arriving at the answer (all the little details as well if possible) as I can't quite seem to work them out correctly. Thanks.
