Hello, 
We can let x represent the second angle. Also we know every triangle has 180 degrees so the equation will look like:
x + 4x + (2x+5) = 180
Combine like terms and subtract 5 from both sides to get:
7x=175
Now divide both sides by 7 to result in:
x=25 degrees for the second angle
Other two angles are: 100 and 55 degrees. 
Make sense?
