Question

Given: ΔABC, AC = BC, AB = 3 CD⊥ AB, CD = 3 Find: AC

Answer 1

Answer:

3$\sqrt{5}$/2

Step-by-step explanation:

As given, AC = BC, its an isosceles triangle.

Now, CD is perpendicular to AB, therefore AD = DB = 0.5AB = 3/2

Now take triangle ACD,

using Pythagoras theorem,

AC = $\sqrt{AD^{2} + CD^{2} }$

AC = 3$\sqrt{5}$/2
