Ahmad = 1/6
Barry = 1/2
Tara = 1 - 1/6 - 1/2 = 1/3
1/3 of the seashells = 76
3/3 of the seashells = 76 x 3
3/3 of the seashells = 228

Answer = 13 3/7
Step-by-step explanation:
3cos2x +sinx=1
3(1-2sin²x)+sinx=1
3-6sin²x+sinx=1
sinx(-6sinx+1)=1
either
sinx=1
sinx=sin(90)
:.x=90
or
-6sinx+1=1
-6sinx=1-1
sinx=0/-6
sinx=sin0,sin180
:.x=0,180and90
