Answers

Answer:

the answer its c 122 is angle 1

Answer:

A. 32

Step-by-step explanation:

The two angles are equal to each other so you can set them equal and solve

2x+57=6x-71

Add 71 to both sides

2x+57+71=6x+0

2x+128=6x

Subtract 2x from both sides

128=6x-2x

128=4x

Divide 4 from both sides

128/4=x

32=x

Explain how to tell if two terms are alike. Show one pair of like terms that each contain at least two variables. Show how to add these like terms. Then show a second pair of terms that are NOT alike, but share some of the same variables. Explain why they are not alike

Answers

Answer:

hey

Step-by-step explanation:

In order to tell if two terms are alike, check it’s variables. If they have the same variables they are like-terms. For example, 2kl + 3kl are like terms because they have the same variables. In order to add them, you need to add the coefficients. A pair of terms that are not alike are 3kl and 5kps. They are not alike because they don’t have the same variables.

The area of the new poster is double the area of the small poster.
The area of the new poster is four times the area of the small poster.
The area of the new poster is one-half of the area of the small poster.
The area of the new poster is one-fourth of the area of the small poster.

Answers

Answer:

The first answer.

Step-by-step explanation:

Manuel doubles the size of the poster, so the area is doubled!

Answer:

The answer is the first one.

Step-by-step explanation:

The other ones do not make any sense, the area of the new poster can not be four times bigger, because it was only doubled. It can't be 1 half, because it got bigger. And same goes for it being 1 fourth.

Answers

Answer:

It should be 58 degrees. Good luck and have a nice day!

Step-by-step explanation:

If the angle on the opposite side is 32 degrees and the angle right next to it makes a 90 degree angle then the one on the opposite side is also 90 and 32. So just subtract 32 degrees from 90 and you get 58 degrees.

(sorry if that's confusing)

Answer:

58

Step-by-step explanation:

Use the right angle to find the missing angle. We know the one angle is 32.

90-32= 58

58 and your angle s are equal to each other because they are opposite angles.
