Answer:

x = - 3

19x = 5x - 42 ( subtract 5x from both sides )

14x = - 42 ( divide both sides by 14 )

x = - 3

I really need help find x in this triangle
arsen [322]

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

72 + 6x + 2 + 17x - 9 = 180

23x + 65 = 180 ( subtract 65 from both sides )

23x = 115 ( divide both sides by 23 )

x = 5
