Question

in a triangle abc angle b is equal to 90 degree and ac is equal to 8 root 2 if ab is equal to BC then find AB​

Answer 1

Answer:

The answer is 8.

Step-by-step explanation:

AB = AC

By pythagoras theorem,

(AC)² = (AB)² + (BC)²

(AC)² = (AB)² + (AB)²

(AC)² = 2(AB)²

(8root 2 )² = 2(AB)²

128 = 2(AB)²

(AB)² = 128 ÷2

(AB)² = 64

AB = 8

Therefore, AB is 8cm.
