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.

Limit Rule [Variable Direct Substitution]: 
Step-by-step explanation:
*Note:
For a limit to exist, the right-side and left-side limits must be equal to each other.
<u>Step 1: Define</u>
<em>Identify</em>
<u>Step 2: Find Left-Side Limit</u>
- Substitute in function [Left-Side Limit]:
- Evaluate limit [Limit Rule - Variable Direct Substitution]:
<u>Step 2: Find Left-Side Limit</u>
- Substitute in function [Right-Side Limit]:
- Evaluate limit [Limit Rule - Variable Direct Substitution]:

Answer:
9/14
Step-by-step explanation:
You multiply the two fractions. So 5/7*9/10, you just multiply across. This would give you 45/70. Then, after simplifying, this fraction is 9/14. So, Sean ran 9/14 of a mile on Sunday. Hope this helps, Sorry if im wrong!!
