You add 5x to 2x+2, 7x+2. Set this equation equal to 80, 7x+2=80 solve and you will get 11.1428571429. Round this number to 11, 11.1, or 11.14.
Answer:
Step-by-step explanation:
Alright, lets get started.
The three angles are : 80, (2x+2) and 5x
As we know these three angles are of a triangle's angle it means, their sum should be 180 .
So, adding these three angles and making them equal to 180, then :
[tex]80+(2x+2)+5x=180[/tex]
[tex]82+7x=180[/tex]
[tex]7x=180-82[/tex]
[tex]7x=98[/tex]
[tex]x=\frac{98}{7}=14[/tex]
So, the value of x is 14 : Answer
