You move down from those coordinates
X stays the same while it just moves down only Y changes
9x-4=5x-6
+4 +4
9x=5x-2
-5x-5x
4x=-2
divide by 2 on both sides
x=-2 or
x= 4/9
You're given an angle, the side adjacent to the angle, and are looking for the hypotenuse.
Use cosine = adjacent / hypotenuse.
cos(60) = 2√(3) / x
Rearrange the equation to solve for x (multiply both sides by x, then divide both sides by cos(60)).
x = (2√(3)) / (cos(60))
x equates to about 6.928
It has no correlation so C.
Answer:
1. c=-2
2. 0=12 no solution
3. x=4
4. r=3/2
