A)
Because the sum of angles in a triangle must equal 180° we can say:
62+α+90=180
α+152=180
α=28°
b)
Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:
b+b+b=180
3b=180
b=60°
Answer:
D
Step-by-step explanation:
Up to 400 pages, the cost is fixed at 5.00 dollars
After 400 pages the cost is 0.01 cents/page
- It's not A. 400 is the number of pages. It is not a cost.
- It's not B either. B means that no matter how many pages you print, it's going to cost 5 dollars + the number of pages times 1 cent.
- C is not the answer. It is really just an answer put it. You pay 1 cent for each page between 400 and what you printed.
- I think D is the answer, but if you get a negative number, then the cost is 5 dollars
Answer:
-600
Step-by-step explanation:
4 x 10 x 3 x 5 x -1
40 x 15 x -1
600 x -1 = -600
