<span>Based on the problems I have recently done on FLVs with this though, is that if you connect the center of the arcs to the top intersection point, if the angle degrees, and opposite arcs are the same then it is an equilateral triangle.</span>
Answer:
![x^{2} +y^{2}=25](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2By%5E%7B2%7D%3D25)
![x^{2} +y^{2}=5](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2By%5E%7B2%7D%3D5)
<em>Radius: 5</em>
<em>Radius: </em>![\sqrt{5}](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D)

3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
1. 35x + 0.15y
=3500x + 15y [multiplying the equation by 100]
= 700x + 3y [dividing the equation by 5]
2. Let x be an even integer
x + (x+2) + (x+2+2)
x+x+2+x+4
3x+6
3. 1/5*(r+7) - 9s
(r+7)/5 - 9s
4. x=cows
y= goats + sheep
x= (y+140)/2
Answer:
sin 60° = 0.9
Step-by-step explanation:
sin 60° = cos 30°
cos 30° = 0.866025403
0.866025403 to one significant figure
0.866025403 ~ 0.9
~. means approximately.
therefore sin 60° = cos 30°
sin 60° = 0.9
