Answer:x=31

angle AOC = 124

angle BOC = 56

Step-by-step explanation:

We first need to solve for x to solve the rest. We would normally solve for x by setting 2 equations equal to each other, in this case however, we know that the two angles are adjacent and in total add up to 180. Therefore we combine like terms of both angles, and set them equal to 180.

So, we do

3x+31+2x-6=180 We will combine like terms

5x+25=180 Now we will do inverse operations

5x=155

x=31

We plug x into angle AOC to solve for it

3(31)+31= 124

180-124=56 or angle BOC because the whole angle is 180, and if we subtract 124 from 180 we get the remainder which is angle BOC

Or if you want,

2(31)-6=56

Which represents the value of c?

zhuklara [117]

B. c = ((3)sin45°)/sin40°

Side a is given information: 3cm, and we can find angle A (which is the angle opposite side a) by subtracting the other two angles from 180 because the total interior angle measures of a triangle add to equal 180°.

Angle A = 180 - (95+45) = 40°.
This can be substituted into the equation for the law of sines.

sin(40)°/3 = sin(45)°/c
—Cross multiply
c•sin(40)° = 3•sin(45)°
—divide both sides by sin40 to get the variable c alone and we get:
c = (3)sin(45°)/sin(40°)

this also simplifies to 3.3 cm.

You roll a die twice. Solve for the probability. P(3, then even)

Monica [59]

For the first roll, you expect that you would get number 3 of a die.
Next for the second roll, you expect that you would get an even number. Since there are 6 sides of a die, so the even numbers are only 2, 4 and 6.

Use a table of values to find the solution to the equation f(x)=h(x) where

GuDViN [60]

9514 1404 393

Answer:

x = 2 1/3

Step-by-step explanation:

We can examine the equations to see where the solution lies.

f(x) = (2/3) -x

This has an x-intercept where y=0, at x=2/3. It has a y-intercept where x=0, at y=2/3. Its slope is -1.

h(x) = 3 -2x

This has an x-intercept where y=0, at x=3/2. It has a y-intercept where x=0, at y=3. Its slope is -2.

In the first quadrant, the graph of h(x) is farther from the origin and steeper than the graph of f(x). The lines must cross in the 4th quadrant at some value of x that is greater than 3/2. The fraction in the definition of f(x) suggests that the solution will be a multiple of 1/3.

The attached table shows a couple of guesses at values of x that would make f(x) = h(x). We find that x = 7/3 is the solution we're looking for.

The scatterplot shows the distance (in feet) that a person was from a motion sensor during an experiment in math class. Use the

iragen [17]

Answer:

B.) 27ft

Step-by-step explanation:

The labeled points given: (5,18) and (1.5, 7.5)

Slope = (18 - 7.5)/(5-1.5) = 10.5 / 3.5 = 3

A linear model:

y - 18 = 3(x - 5)

y - 18 = 3x - 15

y = 3x + 3

If x = 8 seconds then the distance in feet (y) would be: (plug in x = 8 into the equation y = 3x + 3)

y = 3(8) + 3

y = 24 + 3

y = 27 ft

Answer:

B.) 27ft
