Korvikt [17]

The answer to the question is 112°

First, you must set up an equation to find x.

2(3x+10)+2(2x)=360\\

Then, you must use distributive property to simplify the parentheses.

6x+20+4x=360

Next, add like terms.

10x+20=360

Then, subtract 20 on each side.

10x=340

Next, divide 10 on each side.

x=34

Now, you must substitute 34 in for x.

3x+10

3(34)+10

3(34)+10=112
