One angle of a triangle is three times as large as another. The measure of the third angle is 65 more than the smallest angle. What are the measures of each angle

Angles are a, b, c,

 

a + b + c = 180

 

a = 3b

 

c = b + 65

 

 

Substitution

 

3b + b + b + 65 = 180

 

5b + 65 = 180

 

5b = 115

 

b = 23

 

EDIT: deleted the last part of the answer cuz yall know why

(180-65) /5 = 23        angles are:  69,   23,  and 88  smiley
