Question

i need help solving for X =

Answer 1

Answer:

x=12

Step-by-step explanation:

The sum of the angles of a  triangle is 180 degrees

<A + <B + <C = 180

6x+11 + 3x+2  + 5x-1 = 180

Combine like terms

6x+3x+5x +11+2-1 = 180

14x+12 = 180

Subtract 12 from each side

14x+12-12 =180-12

14x = 168

Divide by 14

14x/14 = 168/14

x=12

Answer 2

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

6x + 11  + 3x + 2 + 5x - 1 = 180

6x + 3x + 5x  + 11 + 2 - 1 = 180

Combine like terms

14x + 12 = 180

Subtract 12 form both sides

14x = 180 - 12

14x = 168

Divide both sides by 14

x = 168/14

x = 12
