Answer 1

Answer:   Anwser is 10.5

Step-by-step explanation:

Alright, lets get started.

Given that

$AB=4$

$AC=6$

$AD=7$

Since triangle ABD and triangle ACE are similar triangles, so

$\frac{AB}{AC}=\frac{AD}{AE}$

$\frac{4}{6} =\frac{7}{AE}$

Cross multiply

$4 \times AE = 6 \times 7$

$AE=\frac{42}{4}$

$AE=10.5$

Hence the answer is 10.5     .... Answer

Hope it will help :)
