Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)
The answer would end up being 5.
Answer:
The domain can't be found by this equation u have to look at the question one more time because it should say what it is.
Step-by-step explanation:
Well, there's a lot of ways you could do this. Because it's multiple choice, you can just pick a pair of points and whatever equation it works in, that's your answer. In this case, it's the third one down.
If you didn't have multiple choice you would use these two formulas:
m = (y2 - y1)/(x2-x1)
y - y1 = m (x - x1)
