Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of the four angles formed

vitfil [10]

We have
angle 1= $72 degrees$

see the attached picture to better understand the problem

we know that
Vertical angles are congruent
 $angle1=angle3 \\ angle2=angle4$

and

adjacent angles are supplementary
 $angle2+angle1=180 \\ angle3+angle4=180$

if the measure of one of the angles is $72$ degrees and straight lines equal $180$ degrees you have to
subtract $72$ from $180$
so
$angle 2=180-72 \\ angle 2=108 degrees$

therefore
$angle 3=amgle 1 \\ angle 3=72 degrees$

$angle 4=amgle 2 \\ angle 4=108 degrees$

the answer is

the measures of the other three angles are
$108, 108 and 72 degrees$

Can someone help me with this math homework please!

juin [17]

Answer:

1: (C)

2: (C)

3: (D)

4: (A)

5: (D)

Step-by-step explanation:

1: "Which could be the entire interval over which the function, f(x), is negative?"

When f(x) is negative, that means the values under the f(x) column is negative. As you can see, -16 & -8 are the only times when f(x) is negative. To find the interval, we are going to use x-values. Notice how as x continues to decrease, f(x) also decreases. So the answer is (-infinity, -6).

2: "Which equation represents the graphed function?"

Looking at the graph, we see that the y-intercept is (0, -2). However, all the answer choices have the correct y-intercept, so now we must focus on getting the correct slope. The slope is positive, so the answer is either (A) or (C). To find the correct answer, use the rise/run method from (0, -2) to (4, -1). You rise 1 and run 4, so the slope is 1/4. The answer is y = 1/4x - 2.

3: "If f(1) = 10, what is f(3)?"

I honestly don't know how to do this one. I looked it up on Brainly and some other people said the answer is 30. Credits to dragonheartedking on Brainly.

4: "Which table represents a linear function?"

Table A represents a linear function because each time x increases by 1, y increases by the same amount of 4 each time. It doesn't fluctuate like the rest of the answer choices.

5: "How many units below the y-intercept of g(x) is the y-intercept of f(x)?"

The y-intercept is the point where the function intersects with the y-axis. We start from (0, 2) and count the units as we reach (0, -1). The answer is 3 units.

Mr. De Leon’s Geometry class has 34 students. After lunch everyone returns to the classroom. Within an hour, each person produce

e-lub [12.9K]

Answer:

Heat produced per cubic feet 2.833 BTU per cubic feet.

Step-by-step explanation:

First we find the heat produced by 34 persons.

Heat produced by 1 person = 800 BTUs

Heat produced by 34 persons = 800 * 34 BTUs= 27200BTUs

Now we find the volume of the room that is the space that is occupied by the heat produced by 34 people.

Volume of the room= L*B*H= 25 feet * 32 feet * 12 feet=9600 cubic feet

Dividing the heat produced by the volume will give the heat produced per cubic feet.

Heat produced per cubic feet= 27200/9600= 2.833 BTUper cubic feet.
