Step-by-step explanation:

sin \: 60 \degree =  \frac{27}{k}  \\  \\  \therefore \:  \frac{ \sqrt{3} }{2}  =  \frac{27}{k}  \\  \\  \therefore \: k =  \frac{2 }{\sqrt{3} } \times 27 \\  \\ \therefore \: k =  \frac{2  \times  \sqrt{3} }{\sqrt{3} \times  \sqrt{3}  } \times 27 \\  \\ \therefore \: k =  \frac{2   \sqrt{3} }{3  } \times 27 \\  \\ \therefore \: k = 2   \sqrt{3} \times 9 \\  \\ \therefore \: k = 18   \sqrt{3} \\  \\ \therefore \: k = 18    \times 1.732 \\  \\ \therefore \: k = 31.176 \\  \huge \red{ \boxed{ \therefore \: k \approx \: 31.18 }}\\  \\ tan \: 60 \degree =  \frac{27}{j}  \\  \\  \therefore \:  \sqrt{3} =  \frac{27}{j}  \\  \\ \therefore \: j =  \frac{27}{ \sqrt{3} }  = \frac{27 \sqrt{3} }{3}  = 9 \sqrt{3}  \\ \therefore \: j =9 \times 1.732 \\ \therefore \: j =15.588 \\ \huge \orange{ \boxed{ \therefore \: j \approx 15.59}}

rank has a circular garden. The area of the garden is 100 ft2. What is the approximate distance from the edge of Frank’s garden
Ray Of Light [21]

It is given that the area of the circular garden = 100 ft^2

Area of circle with radius 'r' = \pi r^2

We have to determine the approximate distance from the edge of Frank’s garden to the center of the garden, that means we have to determine the radius of the circular garden.

Since, area of circular garden = 100

\pi r^2 = 100

\frac{22}{7} \times r^2 = 100

r^2 = \frac{700}{22}

r^2 = 31.8

r = \sqrt{31.8}

So, r = 5.6 ft

r = 6 ft (approximately)

Therefore, the approximate distance from the edge of Frank’s garden to the center of the garden is 6 ft.

So, Option A is the correct answer.

PLEASE I BEG FOR HELP! Find mKNL A. 247 B. 184 C. 196 D. 264
fiasKO [112]

Answer:

D. 264°

Step-by-step explanation:

When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs. Therefore,

60° = 1/2[(18x - 6)° - (5x +17)°]

60° * 2 = (18x - 6 - 5x - 17)°

120° = (13x - 23)°

120 = 13x - 23

120 + 23 = 13x

143 = 13x

143/13 = x

11 = x

x = 11

(18x - 6)° = (18*11-6)°= (198 - 6)° = 192°

(5x +17)° = (5*11 +17)° =(55+17)° = 72°

m (arc KNL) = (18x - 6)° + (5x +17)° = 192° + 72°

m (arc KNL) = 264°
