Question

Yadi cot theta =21/20tab cos theta aur sin theta ke man abhi ka little kare

Answer 1

cot theta = 21/20

Tan theta = 20/21

thus

tan theta = perpendicular/ base

by using Pythagoras theorem

${h }^{2} = p {}^{2} + {b}^{2}$

hence,

hypotenuse =

$\sqrt{} (20) {}^{2} + (21 {)}^{2}$

$\sqrt{400 + 441}$

$\sqrt{841}$

= 29

sin theta = 29/20
cos theta = 21/29
