The Length of side AE= 18

Given :

A triangle ABE with the measure of sides .

Explanation :

Find out the measure of AE using similar triangles

From the given figure, Triangle ABE is similar to triangle CDE

When the triangles are similar then the sides are proportional

[tex]\frac{AB}{CD} =\frac{AE}{CE}[/tex]

We know that AB=15, CD=10, CE= 12

Substitute all the values and find out AE

[tex]\frac{AB}{CD} =\frac{AE}{CE}\\\frac{15}{10} =\frac{AE}{12}\\Cross \; multiply \\15(12)= AE(10)\\Divide \; both \; sides \; by \; 10\\\frac{15(12)}{10} =AE\\18=AE\\AE=18[/tex]
