Answer:


x=9

Explanation:

For this you just have to make an equation and in order to do that you have to know that all these angles will equal 180°. Now we can write it out.


3x-4+13x+2+5x-7=180

Now we combine like terms:


21x-9=180

Add the 9 on both sides:


21x=189

Divide the 21 on both sides:


x=9
