Answer:

All to 1 decimal place

3) a = 11.4

4) b = 11.2

5) c = 4.5

6) e = 6.4

7) f = 30.8

8) g = 67.9

Step-by-step explanation:

Step-by-step explanation:

3) cos(18) = a/12

12xcos(18) = a

a = 11.4

4) tan(25) = b/24

b = 24xtan(25)

b = 11.2

5) cos(51) = c/7.2

c = 7.2xcos(51)

c = 4.5

6) sin(28) = e/13.6

e = 13.6 x sin(28)

e = 6.4

7) cos(47) = 21/f

f = 21/cos(47)

f = 30.8

8) sin(33) = 37/g

g = 37/sin(37)

g = 67.9

All to 1 decimal place

Find x .<br><br> Select one:<br> a. 3/4 <br> b. 1/2 <br> c. 2 <br> d. 4
sashaice [31]

we are given

BE=x

ED=x+10

AE=x+1

EC=x+3

we can see that two chords AC and BD are intersecting inside the circle

so, we can use property

AE*EC=BE*ED

now, we can plug values

(x+1)*(x+3)=(x)*(x+10)

now, we can multiply them

x^2+4x+3=x^2+10x

now, we can move all terms on left side

x^2+4x+3-x^2-10x=0

3-6x=0

x=\frac{1}{2}...............Answer

1B (decimal): 0.16 (6 continues)

1C (percent): 16.66 (6 continues)

2.

5+15+7+8+10+15=60

10/60 time she got 5

1/6 chance she gets a 5 again

2A (fraction): 1/6

2B (decimal): 0.16 (6 continues)

2C (percent): 16.66 (6 continues)

3.

Yellow: 3/10 chance

Red: 1/5 chance

Blue: 2/5 chance
