Yes, that's a true statement. It's either a theorem or
a corollary to a theorem in elementary geometry.
To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
Area of course also just a reminder Area is measured in square units such as square centimteres, square feet, square inches, etc
the domain of f(x)= x2 +1 is limited to {0,1,2,3)
the maximum value will be at the maximum value of x which is at x = 3
So, the maximum value of the range will be = 3^2 + 1 = 9 + 1 = 10
Answer:
36 miles
Step-by-step explanation:
(Imagine a huge triangle on a perfectly open space-- not with streets or houses or cornfields.)
The dimensions of the two sides given are multiples of a classic Pythagorean Triple: 3, 4, 5. 
9 is 3x3, 12 is 3x4 so the remaining side would be 3x5 15
Add those 3 sides to get the total distance, 36 miles.
