The first one is -763.1 and the second one is -24
Here is your answer wish you good luck
I don't have my calculator handy just now. But just looking at that problem, why don't you try +20 and -45 and see if they do the job.
The answer would be 3.33333. I think because 10*15= 150. Then you would divide it by 45 and you would get 3.333. If you get it wrong im sorry.
We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to

, and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to
