the missing number should be the square root of the last number times 2 for a perfect trinomial
so square root of 49 = 7
7*2 =14
so the missing number should be 14
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.

I will mark you brainly Answer the following questions. Questions What is an amount between $2 and $10? (A) __________ What is an amount between $10 and $20? (B) __________ What is an amount greater than $50? (C) __________ What is your name? (D) _________________ What is the name of an item that you will buy only once? (E) _________________ What is the name of an item that you will buy more than once? (F) _________________ Create a word problem that leads to an inequality by filling in the blanks with your corresponding answers. Word Problem (D) _________________ is going shopping for (E) _________________ and (F) _________________. The cost of (E) _________________ is (B) __________ and the cost of each (F) _________________ is (A) __________. If (D) _________________ can spend at most (C) __________, how many (F) _________________ can be purchased? Write an inequality of the form Ax + B ≤ C to represent the word problem using your answers for A, B, and C. Solve the inequality and show your work. Graph the solution to your inequality on a number line or describe, in words, how to graph the inequality on a number line. Explain what the solution means in the context of the word problem.
To find the slope of the line, you need two points.
(-2 , 5) and (3 , -5)
5 - (-5) / -2 - 3
10 / -5 = -2
The slope of the line is -2. So your answer is C.
