Answer:
The answer is C. You need to cut it in half.
The law of cosines can be helpful here. The largest angle (C) will be opposite the longest side (c). That law tells us ...
... c² = a² + b² -2ab·cos(C)
Then
... cos(C) = (a² +b² -c²)/(2ab)
We don't actually need the angle. We only need to know the sign of the cosine.
... cos(C) = (7² +15² -17²)/(2·7·15) = -15/210 . . . . negative sign, so C > 90°
The sail has the shape of an obtuse triangle.

Answer:
4 remainder .43
Step-by-step explanation:
Answer:
D. 4 23/24
Step-by-step explanation:
1 7/8 = 1 21/24
6 5/6 = 6 20/24
6 - 1 = 5
20 - 21 = -1
5 - 1/24 = 4 23/24
How to solve?: First you will get you alike terms on the same side. You will do this by subtracting 5 on both sides of your sign and will therefore get the equation to where -5 and -3 is on the same side and looks like -5 - 3. Then you will combine your -5 and -3 and get -8. Now you will take your -2x and divide both sides by -2 to where your able to get your variable x alone. You will then get -8 divided by -2 and your answer would be -4.
Answer: -4
