Help me please I’m struggling to much
forsale [732]

Answer:

\frac{16}{5} or 3.2

Step-by-step explanation:

The given triangles are similar, meaning that their corresponding sides are proportional.

The length of DC (I think its D) is 15 and the length of WZ is 3. ZY is in the same place as CE (16). Make a proportional relationship where Δ→Δ:

\frac{large}{small} =\frac{large}{small}

\frac{DC}{WZ}=\frac{CE}{ZY}

Insert the known values:

\frac{15}{3}=\frac{16}{x}

x is the value of ZY. Solve by cross multiplying:

15(x)=3(16)\\\\15x=48

Divide both sides by 15:

\frac{15x}{15} =\frac{48}{15} \\\\x=3.2

ZY is 3.2.
