Answer:
hypotenuse
Step-by-step explanation:
Remember that when using sin and cos functions, the hypotenuse is always included as the denominator of the equation EXCEPT when you're solving with tan, which is opposite/adjacent.
I think 17.2 sorry if im wrong
(1,3)(3,5)
slope = (5-3) / (3-1) = 2/2 = 1
(3,5)(4,7)
slope = (7-5) / (4-3) = 2/1 = 2
False....they are not collinear because they have different slopes and do not lie on the same line
