Answer:

\frac{5\pi}{3}  \: ft

Step-by-step explanation:

l =  \frac{100 \degree}{360 \degree}  \times 2\pi \: r \\  \\  = \frac{5}{18}  \times 2\pi \:  \times 3 \\  \\  =  \frac{5\pi}{3}  \: ft

In the triangle shown above m∠B = 114°, m∠C = 22°, and b = 12 in. What is the approximate length of side a? A. 15.78 in B. 9.12
Elena L [17]

The approximate length of side a is 9.12 in. The correct option is B. 9.12 in

<h3>Law of Sines </h3>

From the question, we are to determine the approximate length of side a

From the given information, we have that

m∠B = 114°, m∠C = 22°

Thus,

m∠A = 180° - (114° + 22°)

m∠A = 180° - 136°

m∠A = 44°

Now,

From the law of sines, we have that

a/sinA = b/sinB

Then,

a/sin44° = 12/sin114°

a = (12 ×sin44°)/sin114°

a = 9.12 in

Hence, the approximate length of side a is 9.12 in. The correct option is B. 9.12 in

Which glide reflection describes the mapping triangle ABC triangleDEF?
ZanzabumX [31]
In order to visualize the transformations, we must execute the transformation in the options

The first transformation would shift triangle ABC 3 units to the left and reflect it across x = 4. This will not map ABC unto DEF.

The second transformation would shift triangle ABC 7 units down and reflect it across x =4. This will map ABC unto DEF,

So, the answer is the second option.

nordsb [41]

The partial blueprint of a house that includes 3 bedrooms is shown below. The scale is 2.75 inches : 3 feet. What is the actual length and width of Bedroom 3 in feet?

Bedroom 1 w=9.17; l= 11 in

Bedroom 2 w=7.33 in; l= 12.83

Bedroom 3 w= 11 in; l= 14.67 in​

______________________________________

___________

2.75 inches : 3 or 2.75 in / 3 feet

________________

Can you see the updates?

______________

Bedroom 3 w= 11 in; l= 14.67 in​

11 in * 3 feet / 2.75 in = 12 feet

14.67 in​ 3 feet / 2.75 in = 16 feet

_________________________

Answer

Bedroom 3 w= 12 ft ; l= 16 ft

I Need Help With These
Dmitrij [34]
Notice below the picture

the one on the left-hand-side, is the 30-60-90 rule

those are the ratios, for 16), the hypotenuse (slanted side), is 4

for the ratios, that means that 4 = 2x, if you solve that for "x", that simply means "x" is 2

now, just use that value you found for "x" from the hypotenuse ratio, and use it to get the other two sides

what's the perimeter? all three sides added together

for 17)     \bf \textit{area of an equilateral triangle}\\\\&#10;A=\cfrac{s^2\sqrt{3}}{4}\qquad s=\textit{length of one side}
