the perimeter of a triangle is 76cm.side a of the triangle is twice as long as side b.side c is 1 cm longer than side a. find the length of each side

a is 2x  b is x  c is 2x plus 1 2x plus x plus 2x plus 1  Combine all terms  5x plus 1  subtract 1  75 divide by 5 = 15 a is 30 b is 15 c is 31

first you going need to take 76 times 2 and than add 1 cm and the divide by the 3 sides and tha thsould get your answer :0 good luck
