In a certain triangle the measure of one angle is triple the measure of a second angle but is 110 degrees less than the measure of the third angle. [The sum of the measures of three interior angles of a triangle is always 180 degrees.] What is the measure of each angle?

just write it algebraically:

b = 3a
b = c-110
a+b+c=180

a + 3a + (110+3a) = 180
7a = 70

a=10
b=30
c=140
