Find ac. Round to the nearest tenth

Mathematics

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

If mC = 90°, side c = 29, and side a = 21, then side b = 18.

Triss [41]

The 3 sides should obey the Pythagorean Theorem
29^2 = 21^2 + 18^2
29^2 does not equal 441 + 324 = 765
29^2 = 841

The following data points represent the volume

maks197457 [2]

Answer:

The missing volume of gas is 6 liters

Step-by-step explanation:

The following data points represent the volume of gas in each race car driver's tank (in liters):

4,5, 13, ?

Let the missing value be x

Data : 4,5,13,x

$Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}$

$7 = \frac{4+5+13+x}{4}$

$7 \times 4=4+5+13+x$

28=22+x

28-22=x

6=x

Hence The missing volume of gas is 6 liters

I have to find the value of x

Greeley [361]

Answer:

x = 25

Step-by-step explanation:

A quadrilateral is inscribed in a circle, so it is a cyclic Quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

3x + 21y = 180°.....(1)

2x + 26y = 180°.....(2)

From equations (1) & (2)

3x + 21 y = 2x + 26y

3x - 2y = 26y - 21y

x = 5y

y = 1/5 x

Plug y = 1/5 x in equation (1)

3x + 21*1/5x = 180

15x + 21x = 180*5

(Multiplying both sides by 5)

36x = 900

x = 900/36

x = 25
