the first angle of a triangle is 24 degrees less than the second angle. The third angle is three times the second angle. use x to represent the unknown value
Thank you for the opportunity to help you with your question!
let the second angle is x
first angle = x-24
third angle = 3x
total of all angles =180 degrees
first angle = 40.8-24 = 16.8
third angle = 3*40.8 = 122.4
