Answer: This is an acute triangle. x=115°
9514 1404 393
Answer:
(x, y) = (5, 4)
Step-by-step explanation:
Subtracting the second equation from the first eliminates the x term.
(4x +6y) -(4x +2y) = (44) -(28)
4y = 16 . . . . simplify
y = 4
Using the second equation to find x, we have ...
4x +2(4) = 28
x + 2 = 7 . . . . . . divide by 4
x = 5 . . . . . . . . . subtract 2
The solution is (x, y) = (5, 4).
Answer:
240 ft^2
Step-by-step explanation:
If you know you have 6 triangles then you can just find the area of one and then multiply by 6. First find your formula: (b)(h)/ 2
Next plug in: (8)(10)/2 = 40
Now you know the area of one so multiply by 6: (40)(6) = 240 ft^2
Answer: About 4 movies
Step-by-step explanation:
1 2/3 times 4/1 = 28/5
28/5 converted to a mixed number is 5 3/5
