Question 2928
 
    Let the measure of angle c = x
 
    So the measure of angle b = x-5
 
    & the measure of angle a  = 3x
 
    Sum of the angles in a triangle is = 180
 
    So,  3x + x-5 + x = 180
 
    =   5x-5  = 180
 
    =   5x = 180+5 = 185
 
    =    x = {{{185/5}}} = 37
 
    So angle a = 37*3 = 111;   angle b = 37-5 = 32;  angle c = 37. Answer
 
    Is it clear?
