In this rectangular box, EF = 16, FD = 5, and DB = 30. Find AF.

AVprozaik [17]

Answer:

FA = 25.87

Step-by-step explanation:

Given: BD = 30 , DF = 5 , EF = 16

To find: FA

Rectangular box is a Cuboid.

Figure attached.

AB = FE = 16

So,

In ΔADB

using Pythagoras theorem,

$DB^2=AB^2+AD^2\\30^2=16^2+AD^2\\900=256+AD^2\\AD^2=900-256\\AD^2=644\\AD=\sqrt{644}\\AD=2\sqrt{161}$

Again using Pythagoras theorem in Δ ADF we get

$FA^2=DF^2+AD^2\\FA^2=5^2+(2\sqrt{161})^2\\FA^2=25+644\\FA^2=669\\FA=\sqrt{669}\\FA=25.87$

Therefore, FA = 25.87
