a triangle has one angle measuring 3x degrees. a second angle measures 2x+20 degrees and the third angle measures 4x-20 degrees. what is the value of x?

Answer provided by our tutors

The sum of measures of the three angles of any triangle is equal to 180 hence we can write:

3x + (2x + 20) + (4x - 20) = 180
