Some please answer fast. Please.

Answer 1

Answer: 42

Explanation:

Ok what you want to do is add all of them up and equal it to 180 because a triangle is 180 degrees .

Your equation should look like this

9x-3+22x+1+42-3x = 180

What you want to do first is combine all the x and numbers on the left side so it should look like this

1) 28x+40= 180

Then you want to subtract 40 on both sides so it will look like this

2)28x=140

You want to get x by it self so you divide 28 on both sides

3) x=140/28

4) x=5

Since you are finding c you have to insert 5 into x

1) 9(5)-3

2)45-3

Then your answer should be 42
