Question

In the diagram, CD 1 AC, BE 1 AC, AE = 17, BE = 8, and CD = 32. Find DE. 32 D В E 8 17 A 45 51 O 68 O 35 Question 3 1 pts a HE

Answer 1

Input data

AE = 17

BE = 8

CD = 32

Procedure

`\begin{gathered} (AD)/(AE)=(CD)/(BE) \\ (AD)/(17)=(32)/(8) \\ AD=17\cdot(32)/(8) \\ AD=68 \end{gathered}`

Now for DE

`\begin{gathered} AE+DE=AD \\ DE=AD-AE \\ DE=68-17 \\ DE=51 \end{gathered}`

The answer would be DE=51
