Answer: 29.7 degrees

Step-by-step explanation:

Good, I can see the diagram now!

First calculate circumference of the circle.

C=2πr

C=2π(27)

C=54π in ==> 360 degrees

54π/14=12.11757

360/12.11757=

29.709=29.7 degrees

3x+y=19 \\
x+3y=1 \\ \\
\hbox{add the sides of the equations:} \\
3x+x+y+3y=19+1 \\
4x+4y=20 \\ \\ \hbox{divide both sides by 2:} \\
2x+2y=10

The answer is d. 10.

Gre4nikov [31]

Answer: your mom gay ;)

Step-by-step explanation:

4,500 calories a day

If you ate the same amount each day, that means you would eat 3 a day, since 6 divided by 2 is 3.

Find how many calories you would eat each day by multiplying 3 by 1,500

3(1,500)

= 4500

How would you also do this??
Vesna [10]

4(5x + 7) = 128

First, I'd do distributive property and get:

20x + 28 = 128

Then, subtract 28 from each side.

20x = 100

Next, I'd divide 100 by 20 = 5

x = 5

4 *(5(5) + 7) = 128

5 * 5 = 25

4 * (25 + 7)

4 * 32 = 128

Therefore, the perimeter = 2l + 2w

l = 4

w = 5x + 7

BUT we know that x = 5

w = 5(5) + 7 = 32

2(4) + 2(32)

8 + 64 = 72

Therefore, the perimeter would be 72 inches.

Given:  cos A = 5/13 = adj side / hypotenuse

The the opp side is given by  (hypo)^2 = (adj)^2 + (opp)^2.  Here,
                                                 13^2     =   5^2     + (opp)^2, so that 
(opp)^2 = 169 - 25 - 144.  Then opp = +12.  All of these lengths are in Q I.
                       opp        12
Then sin A = -------- = --------  (answer)
