Question

The angles of a triangle or 80°, 2X +2°, and 5X degrees what is the value of X

Answer 1

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 2

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 :

`80+(2x+2)+5x=180`

`82+7x=180`

`7x=180-82`

`7x=98`

`x=(98)/(7)=14`

So, the value of x is 14 : Answer
