triangle problem
The three angles of a triangle are 3x, x + 10, and 2x - 40. Find the size of the smallest angle in the triangle. Thanks for the help.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

bobbym has correctly computed the value of x.
The three angles are:
3x = 105°
x+10 = 45°
2x-40 = 30°
The smallest angle is 30
