71,290 because the 0 can't make 90 go up.
<span>3) This one is a little different, since you're finding the angle instead of the side. You can denote the angle to be the variable x. Thus:
cos x = 14 / 26
Use a calculator to divide out 14/26, then round to four decimals.
cos x = 0.5385
Now go to the cosine chart and find which angle has the cosine 0.5385. It's a strange problem they gave you, because the chart doesn't have a value that matches it (kind of confusing if you ask me). But you can find two angles it is between. Notice that cos 57° = 0.5446 and cos 58° = 0.5299. Thus, the angle must be between those two. It turns out it is closer to 57°, so you can say:
x = 57° </span>
Answer:
6.5 = x
Step-by-step explanation:
(x - 4)2 = 5
2*x + 2*-4 = 5
2x - 8 = 5
2x = 13
x = 6.5
The first part of your question, you got correct... 13/9 or 1 4/9.
We can assume 2 pizzas because they each ate a part of their pizza. So to get how much is left we just subtract your answer from 2.
2 - 1 4/9 = 5/9
5/9 is left over.
Answer:
Step-by-step explanation: first you would graph them... for the first equation you would start at -2 and go up one left one and for the next equation you would start at 8 and go down one right one
