Find ac. Round to the nearest tenth

Mathematics
1 answer:
nata0808 [166]3 years ago
8 0

Answer:

AC=6.37

Step-by-step explanation:

First you need to find m∠C

A triangle = 180 so you need to add 108 and 31

subtract 180-139

you get 41, so m∠C=41

Now we know all the angle measures.

Next we will use the law of sines

Go to google and type "law of sines calc"

google can usually provide with the formula and will even do the equation for you if you type in the numbers

So all you do is plug in the numbers and google will give you 6.37

I have tested (fog)(x) ,(f*g)(x) and finally (f+g)(x)

f(x)=6x++++++++++++++++++++++++3
g(x)=x-7
(f+g)(x)=6x+3+x-7=7x-4
(f+g)(3)=7*3-4=17

X-5y-z=-20<br><br>-2x-y-6z=25<br><br>-x-4y-z=-15<br>Solve by elimination
Tju [1.3M]

Answer:

x = 0

y = 5

z = -5.

Step-by-step explanation:

X-5y-z=-20

-2x-y-6z=25

-x-4y-z=-15

Add equation 1 and 3:

-9y - 2z = -35 .......... A

Multiply the first equation by 2:

2x - 10y - 2z = -40

Now add this to equation 2:

-11y -8z = -15.............B

Now multiply equation A by -4:

36y + 8x = 140.........C

Add equations B and C:

25y = 125

y = 5.

Substitute for y in equation A:

-9*5 - 2z = -35

2z = -45 + 35 = - 10

z = -5.

Now find x by substituting for y and z in the first equation:

x - 5(5) - (-5) = -20

x - 20 = -20

x = 0.
