Question

Sin theta 21/35 तो cot theta=?

Answer 1

Answer:

sin theta =p/h=21/35

so,p=21 and h=35

using Pythagoras theorom

(h)^2=(p)^2+(b)^2

(35)^2=(21)^2+(b)^2

1225=441+b^2

b^2=1225-441

b^2=784

b=√784

b=28

now,cot theta= h/b=35/28

Answer 2

Answer:

आपका जवाब है

$cot \theta = \frac{14}{21}$

Step-by-step explanation:

$if \: sin \theta \: = \frac{21}{35} \: then \\ {cos}^{2} \theta \: =1 - {sin}^{2} \theta \:$

${cos}^{2} \theta \: = 1 - ({ \frac{21}{35} })^{2}$

$cos \theta = 1 - \frac{21}{35}$

$cos \theta \: = \frac{35 - 21}{35}$

$\bold { cos \theta = \frac{14}{35} }$

$\bold {now}$

$cot \theta = \frac{cos \theta}{sin \theta}$

$cot \theta \: = \frac{ \frac{14}{35} }{ \frac{21}{35} }$

$cot \theta = \frac{14}{35} \div \frac{21}{35}$

$cot \theta = \frac{14}{35} \times \frac{35}{21}$

$\bold{cot \theta = \frac{14}{21}}$
