ang hirap nang tanong

Answer 2

Answer:

value of cos 30 × tan 60 + sin 30 is an integer...

Step-by-step explanation:

cos 30 =

$\frac{ \sqrt{3} }{2}$

tan 60 =

$\sqrt{3}$

sin 30 =

$\frac{1}{2}$

so, cos 30 × tan 60 + sin 30

$\frac{ \sqrt{3} }{2} \times \sqrt{3} + \frac{1}{2}$

=

$\frac{3}{2} + \frac{1}{2}$

=

$\frac{4}{2}$

=

$2$

and 2 is an integer , hence we proved that

cos 30 × tan 60 + sin 30 is an integer.

i hope it helped......
