How do i find the measures of the angles

Over [174]

Do you have a protractor? If so, use it and place the center whole, that is located at the bottom, and place it on the dot of the angle. where the arrow hits, is your angle degree. You should be able to identify the angle type.

M23 is (3x + 4)º and mz5 is (2x + 11)

Tom [10]

9514 1404 393

Answer:

same-side interior
(3x +4) +(2x +11) = 180
77°

Step-by-step explanation:

Angles 3 and 5 are on the same side of the transversal, between the parallel lines, so can be called "same-side interior angles". These are also called "consecutive interior angles". As such, they have a sum of 180°, so are also "supplementary angles." We don't know what your pull-down menu options are, but perhaps one of these descriptions is on there.

__

Because the angles are supplementary, their sum is 180°. So, the equation ...

(3x +4)° +(2x +11)° = 180°

can be used to solve for x. Likewise, any of the possible simplifications of this can be use:

(3x +4) +(2x +11) = 180 . . . . . divide by degrees

5x +15 = 180 . . . . . . . . . . . collect terms

5x = 165 . . . . . . . . . . . . . subtract 15

x = 33 . . . . . . . . . . . . . . divide by 5

__

Once we know that x=33, then the measure of angle 5 is found from its expression:

m∠5 = (2x +11)° = (2·33 +11)°

m∠5 = 77°

Graph the linear equation and answer each of the following questions. y=-2x-3

ollegr [7]

Answer:

Part 1) The y-intercept is the point (0,-3)

Part 2) The slope in fraction form is $m=-\frac{2}{1}$

Part 3) The graph in the attached figure

Step-by-step explanation:

we have

$y=-2x-3$

Part 1) What is the y-intercept?

Remember that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

substitute in the linear equation and solve for y

$y=-2(0)-3\\y=-3$

The y-intercept is the point (0,-3)

Part 2) What is the slope (in fraction form)?

we have

$y=-2x-3$

This is the equation of the line in slope intercept form

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept

so

$m=-2$

In fraction form is

$m=-\frac{2}{1}$

The slope is negative, that means, is a decreasing function (as the x-values increases the y-values decreases)

Part 3) Graph the line

To graph the line we need two points

From the y-intercept (0,-3) use the slope to find your next point

The slope is -2, so you will rise -2 (2 units down) and run 1 (1 unit to the right).

The next point is (0+1,-3-2) -----> (1,-5)

so

Plot the points (0,-3) and (1,-5), connect them and graph the line

The graph in the attached figure

Darron uses a family recipe to make hamburgers. If he plans on using 1 1/3 cups of bread crumbs, about how many pounds of hambur

Viktor [21]

1/4 cups = 1lb mince divide both by three
1/12 cups = 1/3lb hamburgers

1 1/3 cups = 12/12 cups + 4/12 cups
= 16/12 cups
=16 * 1/3lb hamburgers

- as 1/12 cups = 1/3lb burger, 16/12 cups = 16/3 lb burgers
