Hello!
To solve this we use the equation sin60 = (s/2) / (d/2)
s is a side of the triangle
d is the diameter
sin60 = s/d




put 6 in for s


d = 6.9
The answer is C) 6.9
Hope this helps!
Answer:
10 go into 450 45 times
Step-by-step explanation:
90x+60y=72
60y=-90x+72
y=-1.5x+1.2
then create a graph using this formula.
