Using the cosine rule, the equation to use to solve for x is: x = √(4.0² + 4.7² − 2(4.0)(4.7) × cos(41)) ≈ 3.1 cm.
<h3>How to Use the Cosines Rule to Solve a Triangle?</h3>
The cosine rule is given as, c = √(a² + b² − 2ab × cos(C))
Given the following:
- c = x = ?
- a = 4.0 cm
- b = 4.7 cm
- C = 41°
Plug in the values:
x = √(4.0² + 4.7² − 2(4.0)(4.7) × cos(41))
x ≈ 3.1 cm

Omg you need to find the quadrant 1,2,3,4 then once you doo you can put your number
Equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
where (h,k) is the center and r = radius
(x - 3)^2 + (y + 2)^2 = 25
