Question

10. Find the length of each side of a triangle if the perimeter is 73 in. The length of the second side is twice the length of the first side and the length of the third side is five more than thee length of the first side. ​

Answer 1

Explanation:

Given the Perimeter of a triangle is 73

Let the first side be x

second side = 2x

third side = x+5

PERIMETER OF A TRIANGLE = SUM OF ALL SIDES

73=X+2X+X+5

73=4X+5

73-5=4X+5-5

68=4X

68/4=4X/4

17=X

THIS IMPLISE THAT FIRST SIDE IS X = 17

SECOND SIDE IS 2X= 2*17=34

THIRD SIDE IS X+5=17+5=22
