a parallelogram has one angle that measures 40. what are the measures of the other three angles in the parallelogram?

Answers

Since one side is 40°, you subtract that from 180.

180° - 40°= 140°.

So therefore your missing side lengths are 140, 40, and 140.

A parallelogram will always add up to 180 degrees. So if one side is 40 degrees, all you have to do is subtract 180 degrees from 40 degrees and divide by 3 and there you go!!

What is 5d - 10 = 20​

Answers

Here is your equation:

5d-10=20

In this equation, you're looking for the value of d alone. That means you would have to move everything next to the variable to the other side. You can do that by doing the opposite of what's being done to it.

In this equation, 5d is being subtracted by 10(-10). The opposite of that is adding 10(+10). You would have to add 10 to both sides, since -10 and +10 cancel out each other.

The first thing you are going to do is add 10 to both sides.

5d-10+10=20+10 \n 5d = 30

Now you're left with the equation 5d=30. Remember that you're looking for d alone. In the current equation, d is being multiplied by 5(5d ⇒ 5 × d). Again, you're going to do the opposite of what's being done to it. The opposite of multiplying is dividing, therefore, you're going to divide both sides by 5, since the 5 divided by 5 is 1, which cancels out the 5.

Divide both sides by 5.

(5d)/(5) =(30)/(5) \n \nd=6

That means the answer to your equation is d = 6.

Answer:

d = 6

Step-by-step explanation:

Let us follow these steps to make d the subject.

First, add 10 to both sides.

5d - 10 = 20

5d = 10+ 20

5d = 30

Divide both sides by 5.

d = 6

1) The histogram displays the number of years of service for a sample of U.S. Navy veterans. a) How many veterans in the sample had more than 15 years of service?

b) How many veterans are represented by the histogram?

Answers

To find the answer to question A, you must look at all of the sections to the right of fifteen on the histogram's x-axis and add the totals.

4+2 = 6

So, 6 veterans had more than 15 years of service.

For question B, you must add all of the data, in each bar, together. 

25 +12 + 7 + 4 + 2 = 50

So, 50 veterans are represented by the histogram.
A.) I would say twelve because all you have to do is add from 11-15 all the way to 21-25 and it would give you 12
B.)  I would say 48 because you have to add all off the numbers together and you will get 48...
