Question

Find the length of A B in the given figure​

Answer 1

Answer:

1.triangle OCB by Pythagoras-8m

2.triangle OCA by Pythagoras-8m

3.x-8m+8m-16m

Answer 2

Answer:

ab=16cm

Step-by-step explanation:

Δcbx is a right angled triangle. here, length of hypotenuse and one side is given. Using the Pythogoras'  theorem:

         $17^{2} + 15^{2} = xb^{2}$

=  289+ 225= $xb^{2}$

$xb^{2} = 289-225$

$xb^{2} = 64$

$xb = \sqrt{64$

xb = 8

because this is an isoseles Δ  the same steps are to be followed.

Then ab= ax+xb

=> 8+8

=> 16m

Therefore, ab = 16m.
