Answer:

c.6.9 units (to the nearest tenth of a unit)

Step-by-step explanation:

sin60=(s/2)/(d/2)  where s=side of triangle and d=diameter of circle

sin60=s/d

√(3/4)=s/d

d=s/√(3/4)

d=s√(4/3)

d=2s/√3 and since s=6

d=12/√3

d=√48

d≈6.9282

hope this helps:)sorry if it doesnt

How to solve y=-x+4; y=2x-8 using substitution?
Novosadov [1.4K]
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y

-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8   or  y = -(4) + 4
y = 8 - 8          y = 0
y = 0
Final Answer:  y=0, x=4
