the second angle of a triangle is three times as large as the first. the third angle is 30 degrees more than the first. find the measure of each angle. (please include solution, thank you very much)
All angles in a triangle add up to 180. Let's call the first angle x. 180 = x + 3x + 30+x 150 = 5x 30 = x Hence second angle = 30x3 = 90 Third angle = 30 + 30 = 60 To check, 30 + 90 + 60 = 180 (yay)
