Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the3 given angles and equate to 180
x + 6 + 3x - 2 + 7x = 180, that is
11x + 4 = 180 ( subtract 4 from both sides )
11x = 176 ( divide both sides by 11 )
x = 16
Thus
∠ V = x + 6 = 16 + 6 = 22°
∠ W = 3x - 2 = 3(16) - 2 = 48 - 2 = 46°
∠ X = 7x = 7(16) = 112°
