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
Counting numbers are whole integers starting from 1 and going to infinity. It doesn't include negative numbers or zero.
Therefore, the set would be:
{1, 2, 3, 4, 5, 6, 7, 8, 9}

Answer:
118
Step-by-step explanation:
the length ED is equal to EC
so
the angle is also the same
that's mean the angle ECD is equal to 31
then to find the another angle just do like this
=180–31–31
=118
