Question

Help me please I'm confused

Answer 1

Answer is YZ = 14

Step by step

First we know ABCD ~ WXYZ
So we know AD ~ WZ and CD ~ YZ

AD = 12
DC = 3
WZ = 56
YZ = Number (N)

We know sides

3/12 = N/56

Cross multiply

12N= 168

N = 14
Your unknown number of YZ = 14

Answer 2

Answer:14

Explanation:

abcd = wxyz

ad/dc=wz/yz

12/3=4

56/yz=4

yz=14
