Answer:
2.18
Step-by-step explanation:
We will use angle A to solve this and tangent. Tangent in equal to opposite divided by adjacent. In relation to angle A, the opposite side is 6 units and the adjacent side is AC, which we want. This can be set up as
tan70=6/x (x is representing AC)
(x)tan70=6
x=6/tan70
x=2.18
