Answers

Answer:

3 = 21 degrees

5 = 21 degrees

1 = 60 degrees

2 = 39 degrees

4 = 39 degrees

Step-by-step explanation:

This problem is really quite easy once you break it down. I assume you want an answer based on the attachment. If a triangle is Isosceles, then its bottom two angles are congruent, so angle 3 = angle 5.

Then, 138 degrees + x * 2 = 180 degrees.

x * 2 = 42 degrees

x = 21 degrees

So 3 and 5 are each 21 degrees

If a triangle is equilateral, then it is also equiangular, meaning each of its angles are equal to each other, and they are each 60 degrees. Then, we know angle 1 is 60 degrees. For 2 and 4, we want to take the measure of the combination of 2 and 3 (the full 60 degrees), and subtract it by the measure of angle 3 to get the measure of angle 2. 60 - 21 = 39 degrees. Angle 2 is 39 degrees. The same can be done with angle 5 and 4 because they are the same measurements.

In the diagram, ∠AOB and ∠COB form a linear pair. Which statement must be true about the angles?
A. ∠AOB and ∠COB are supplementary to each other.
B. ∠AOB and ∠COB are supplementary to the same angle.
C. ∠AOB and ∠COB are complementary to each other.
D. ∠AOB and ∠COB are complementary to the same angle.
Please give me a serious answer, and if you don't know what to answer then don't, please.

Answers

Answer:

[tex]{{\underline{\textsf{\textbf{A. ∠AOB and ∠COB are supplementary to each other. }}}}}[/tex]

Step-by-step explanation:

As in the question given that, ∠AOB and ∠COB are linear pair and being theses angles are supplements it will form 180°. Hence, option A is the correct ✔️

∠AOB and ∠COB forms a linear pair

∠AOB and ∠COB are supplementary to each other

Given :

In the diagram, ∠AOB and ∠COB form a linear pair.

∠AOB and ∠COB forms a straight line . the sum of angles in a straight line is 180 degrees.

When the sum of angles is equal to 180 degree then they are called as supplementary angles.

∠AOB and ∠COB form a linear pair.

[tex]<AOB +<COB =180[/tex]

the sum of both the angles are equal to 180 degrees .

So, ∠AOB and ∠COB  are supplementary to each other.

Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek. If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?

Answers

Answer:

Eric's father works for 5 hours in the afternoon

Step-by-step explanation:

Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek.

Step 1

The number of hours he works each days is calculated as:

40 hours÷ 5days

= 8 hours per day.

Hence, he works 8 hours per day.

Step 2

We are told in the question that:

If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?

The total number of hours in works in a day = Number of hours worked in the morning + Number of hours worked in the afternoon

Hence:

8 hours = 3 hours + x

x = 8 hours - 3 hours

x = 5 hours

Therefore, Eric's father works for 5 hours in the afternoon

4 consecutive integers have a sum of 22. What is the least of the 4 integers?

Answers

Answer:

The least of the four integers is 4.

Step-by-step explanation:

Let x be the first integer.

x + (x + 1) + (x +2) + (x + 3) = 22

4x + 6 = 22

4x = 16

x = 4

4 + 5 + 6 + 7 = 22

When you subtract a number, you get the same result as when you add the opposite of that number. Why?

Answers

Step-by-step explanation:

Well, the opposite of a number is the same number with the opposite sign. For example, the opposite of -1 is 1.

So, say we have an equation where we're subtracting a number, for example, 2-1, which obviously equals 1. Now, if we add the opposite of 1 to 2, we get the equation 2+(-1) which still equals 1.

In 2011, the school paid $1,050 for 70 students to enter the zoo. In 2012, the school paid $1,395 for 93 students to enter the zoo. How many students would enter the zoo if the school paid $1,425?*​

Answers

Answer:

95 students

Step-by-step explanation:

1260/84 = 15

1,050/70 = 15

1,395/93 = 15

So, it's 15 dollars for every student,

1,425/15 = 95

Check: 1,425/95 = 15
