one angle is five less than three times the measure of another angle together they have a sum of 143



Answer :

x(angle1)+(3x-5)(angle 2)=143(sum of both angles).

x+3x-5=143

combine like terms: 4x-5=143

add 5 to both sides: 4x=148

divide both sides by 4: x=37

substitute for x: angle 1=37, angle 2= 106
