Answer 2

\[(Given) \cos \Theta =\frac{ 3 }{ 7 } (and) 0\le \Theta \le \frac{ \pi }{ 2 } \]
find sin theta and tan theta.

Answer 3

use sin^2 x=1-cos^2x
and tan x =sin x / cos x

Answer 4

my answer:
\[\sin \theta = \frac{ \sqrt{40} }{ 7 }\]

Answer 5

all values are +ve since angle lie in I quadrant.

Answer 6

yes correct

Answer 7

\[\tan \theta = \frac{ \sqrt{40} }{ 3 }\]

Answer 8

is that correct?

Answer 9

yes

Answer 10

thank you so much!

Answer 11

welcome

Answer 12
