Answer:
AB = 35
Step-by-step explanation:
For the value of variable z....;
;Perimetre = 132
; 132 = 2(4z + 3) + 2(5z)
; 132 = 8z + 6 + 10z
; 132 - 6 = 8z + 10z
; 126 = 18z
;the value of...z = 7
Therefore the value of length AB;
AB = 5z...then substitute the value of z into the length of AB
; AB = 5(7)
;AB = 35
Answer:
x = 8
Step-by-step explanation:
since the triangle is isosceles then the 2 legs are congruent, that is both 4x - 3
the perimeter is the sum of the 3 sides , that is
x + 4x - 3 + 4x - 3 = 66
9x - 6 = 66 ( add 6 to both sides )
9x = 72 ( divide both sides by 9 )
x = 8
