Answer:
Step-by-step explanation:
Let the two angles be x and y
Then: y = 5x - 6
And x + y = 180° (the of supplementary angle is 180°)
Putting y = 5x - 6
x + 5x - 6 = 180
6x = 180 + 6
6x = 186
x = 186/6
x = 31°
And y = 5x - 6
y = 5(31) - 6
y = 155 - 6
y = 149°
The angles are 31° and 149°
Answer:
Answer is 5
Step-by-step explanation:
x+2x+3x=30
6x=30
x=5
Answer:
x = 
Step-by-step explanation:
I would subtract 5x and 2 on both sides to get x^2 - 5x - 2 = 0, and using the A = 0, B = -5, and C = -2 to plug it into the quadratic equation which is

*Ignore the A please I cannot get rid of it.*
