Answer:
58 degrees
Explanation:
first find x
5x + 137 = -4x +110
add 4x to both sides
9x + 137 = 110
subtract 137 from both sides
9x = -27
divide both sides by 9
x = -3
that angle is 122
since angle 6 is supplementary to that angle they add up to 180
180 - 122 = 58
angle 6 is 58 degrees
hope this helps :)
