Question 342925
Let x = bigger angle


Let y = smaller angle


x + y = 180


x = 3y + 5


I will solve by substitution.


3y + 5 + y = 180



4y + 5 = 180



4y = 180 - 5



4y = 175



y = 175/4



y = 43.75 degrees.



The smaller angle is 43.75 degrees.



The larger angle is 180 - 43.75 or 136.25 degrees.
