I'm doing the same test... though my inputs are (-6,0) and (3, -4)

Answer:
1 ten.
Step-by-step explanation:
1 ten = 10 ones/units
If sinα=1/4 and it is in q2 it means that the x coordinate is negative.
The triangle has a height of one and a hypotenuse of 4 so:
x=-√(4^2-1)
x=-√15
so tanα=-1/√15
tanα=-√(1/15)
tanα≈ -0.258
