Question

the sum of the angle measures of a triangle is 180. if the first angle is 5 more than 3 times the second angle, and the third angle is 65 larger than the second angle,what are the measurements of each triangle

Answer 1

Break the question down into 3 distinct equations, and then solve for each angle one at a time. 

 

first equation is from: sum of the angle measures of a triangle is 180

second: if the first angle is 5 more than 3 times the second angle

third: third angle is 65 larger than the second angle

 

This gives you 3 variables with 3 equations which allows a solution to be achieved.
