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

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 :

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

$82+7x=180$

$7x=180-82$

$7x=98$

$x=\frac{98}{7}=14$

So, the value of x is 14   :  Answer
