Given the figure below, find EF if CA = (6n) and EF = (n + 8)
GalinKa [24]

Answer:

EF = 12

Step-by-step explanation:

Given

CA =6n

EF= n + 8

Required

Find CN

From the attachment:

EF = CD\ and\ CD = DA

Where

CA = CD + DA

This means that:

CA = CD + CD

CA = 2CD

or

CA = 2*EF

This gives:

6n = 2*(n+8)

Open bracket

6n = 2n+16

Collect anf simplify like terms

4n = 16

n= 4

So:

EF= n + 8

EF = 4 + 8

EF = 12
