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

x-24+x+3x=180

5x=180+24

5x=204

x=204/5

x=40.8 degrees

first angle = 40.8-24 = 16.8

third angle = 3*40.8 = 122.4

Please let me know if you need any clarification. I'm always happy to answer your questions.
