Question

From the given figure in AABC AB IBC, AC=5√2 then (AB) = ?​

Answer 1

Answer:

this question can be solved with the simple trick of height and distance.

Answer 2

Answer:

The length of AB is 5.

Step-by-step explanation:

Here the triangle is a right angled icosceles triangle.

So, we can say that AB = BC.

Now,

(AB)^2 + (BC)^2 = (AC)^2

or, (AB)^2 + (AB)^2 = (5√2)^2

or, 2(AB)^2 = 50

or, (AB)^2 = 25

or, AB = √25

or, AB =5

Therefore, the length of AB is 5.

Verify: (AB)^2 + (BC)^2 = (AC)^2

or, (5)^2 + (5)^2 = (AC)^2

or, 25 + 25 = (AC)^2

or, √50 = AC

or, 5√2 = AC
