Answer:
Step-by-step explanation:
sin θ=1/4,tan θ>0
so θ lies in first quadrant.
cos θ=√(1-sin²θ)=√(1-(1/4)²)=√(1-1/16)=√(15/16)=√15/4


The diagram shows that angle AQB = angle BQC
So 5x= 8x-24
3x= 24
x=8 (first answer)
AQB= 5(8) = 40 (second answer)
BQC= 8(8)-24 = 64-24 = 40 ( third answer)
AQC = AQB+ BQC
AQC= 40+40 = 80 (Fourth answer)
