Question

tan 23 + tan 22 by 1 minus tan 23 into tan 22​

Answer 1

The final answer is "1"

Step-by-step explanation:

$\ Given \ value:$

$\frac{\tan 23+\tan 22}{1-\tan 23\times \tan 22}$

$\ Find \ value= ?\\\\\ Solution:$

$\ formula:\\\\\tan(a+b) =\frac{\tan a+\tan b}{1-\tan a\times \tan b}\\\\\\\therefore \ \ \frac{\tan 23+\tan 22}{1-\tan 23\times \tan 22}\\\\\because \ \ \tan(23+22) \\\\\tan(45)\\\\\tan45^{\circ} = 1$
