A triangle has three angles. The second angle is 6 more than eight times the first angle. The third angle is six less than six times the first. find measurement of each angle.
I need help with this thank you.

You (should) know that the sum of the angles of a triangle always add to 180.
If x = first angle, then 6 + 8x = second angle, and 6x - 6 = third angle.
Add the three together. Set it equal to 180 and solve for x.

x+(8x+6)+(6x-6)=180
15x=180
x=12
first angle = 12
second angle = 102
third angle = 66
