Question

AB = 18.5, AX = 8.1 and BC = 18.5. What
is the length of AC?

Answer 1

AC=16.2 units

Explanation:

we know that

The triangle ABC is an isosceles triangle

so

AX=XC

because triangles ABX and CBX are congruents

AC=2*AX

see the attached figure to better understand the problem

therefore

AC=2*8.1=16.2 units
