Answer:
C
Step-by-step explanation:
Sinፀ = opposite / hypotenuse
sinፀ = 12mm / 48mm
ፀ= Arcsin(12/48)
=16.7°
Of means multiplication
So

And then simplify the numerator ad denominator
=

And simplify the numerator and denominator again
=

And we are finally left with the answer which is
Where the heck did x come from!
Step-by-step explanation:
I think the answer should be y = 36 ( 3x) as the numbers in the sequence are being divide by 3
Y- y1 = m (x-x1)
y+1 = 4(x+3)
y+1=4x+12
y=4x+11
