A central angle θ in a circle of radius 5 m is subtended by an arc of length 6 m.
Marina86 [1]

Answer:

θ=1.2 rad=68.7549°

Step-by-step explanation:

Given

  • Circle of radius 5
  • Arc of length 6 subtends angle of θ

\text{Arc Length}=\text{Radius}\times \text{Angle Subtented(in rad)}

⇒

6= 5\times \text{O}\\

θ=\frac{6}{5} =1.2rad

Therefore θ=1.2 rad

(π rad= 180°)

Therefore 1.2 rad= 68.7549°

(fx+cd)/(x-f)=1/2 solve for x
sesenic [268]

Answer:

Step-by-step explanation:

(fx+cd)/(x-f)=1/2

Cross multiplication,

2*(fx + cd) = 1 * (x-f)

2fx + 2cd = x - f

2fx - x  = -2cd - f

x (2f - 1) = -2cd -f

x = (-2cd-f )/ (2f-1)
