Answer 2

Answer:

Here's your answer!!

13 cm

Step-by-step explanation:

The following figure can be divided into two triangles as ∆ A and∆b

Now at first we have to find the unknown side of∆A by Pythagorean theorem formula

P²+ B²= H²

4²+ 3²= H²

16+9= 25

25= 5²

therefore H= 5

Now we get two sides of triangle B

So now by same formula Pythagorean theorem

we can find AD

(AC)²+ (CD)²= (AD)²

5² + 12²=( AD)²

25+ 144= 169

169= 13²

therefore AD = 13 cm
