you know the three angles add up to π, so if the 1st angle is x, then
x + (2x - π/18) + (2x - π/18 + 5π/36) = π
5x + π/36 = π
and finish it off
Find the angle measures of a triangle (in degrees) if the
second angle measures π/18 less than twice the first, and the
third angle measures 5π/36 more than the second.
Can anyone help me here? im stuck in this part of the quiz
