Answer:
I believe the radius is half the circle which makes the diameter 2x the radius which is 35+35= 70
So to divide the 8/9 by 2/9, just divide the numerator of the 8/9 by the numerator of 2/9. 8 / 2 = 4, so there are 4 groups of 2/9 in 8/9.
Then, Toby can make 4 bags of trail mix that are 2/9 pounds each.
Hope this helps!
To solve the value of x we use the sine rule that states.
a/sinA = b/sinB = c/sinC
Where a, b, and c are the opposite sides of angle A, B. and C respectively.
x/sin60 = 7/sin80
x =(7sin60)/sin80
= 6.062/0.9848
=6.155696691
To 3 significant figures the answer is 6.16
