Answer:
Add 360° to find a positive coterminal angle. Subtract 360° to find a negative coterminal angle. Angles that measure 240° and –480° are coterminal with a –120° angle.
Step-by-step explanation:
So since angle A is 120, so angles B+C=60 because there are 180 degrees in a triangle. So B:C is 2:1. So angle B is 40 and angle C is 20.
Answer:
B = ±X
Step-by-step explanation:
A^2 + B^2 = A^2 + X^2
Subtract A^2 from each side
A^2-A^2 + B^2 = A^2-A^2 + X^2
B^2 = X^2
Take the square root of each side
sqrt(B^2) = ±sqrt(X^2)
B = ±X
Yes, this is a function because the mapping is one to one. The domain is the the different inputs that can be put into the function, so the domain is {1,2,3,4,5}. The range is the different outputs the function can produce. So the range would be {40,80,120,160,200}.
