Answer:
Both A and B
Step-by-step explanation:
For functions you are just trying to make sure all the x's are different.
So let's look at A: The x's there are all different so it is a function
Now let's look at B: The x's there are all different so it is a function.
Both A and B
Answer:
2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using sine rule
SinA/a = SinB/b = SinC/c
A = 84° a = BC, C = 51°, c = 16
Sin84/BC = Sin51/16
Cross multiply
BC Sin51 = 16 × Sin84
BC = 15.91/Sin51
BC = 20.48unit
