Question

If Cos A=7/25 find the value of Sin A and Tan A

Answer 1

Hope it helps........

Answer 2

$Sin A = \frac{Perpendicular}{Hypotenuse} =\frac{24}{25}$

$Tan A = \frac{Perpendicular}{Base}=\frac{24}{7}$

Step-by-step explanation:

$Cos \theta =\frac{base}{Hypotenuse}$

We are given that $Cos A = \frac{7}{25}$

On comparing

Base = 7

Hypotenuse = 25

To find perpendicular

$Hypotenuse^2 = perpendicular^2 +base^2$

$25^2= perpendicular^2 +7^2$

$25^2-7^2=perpendicular^2$

$\sqrt{25^2-7^2}=Perpendicular$

$24 = Perpendicular$

$Sin A = \frac{Perpendicular}{Hypotenuse} =\frac{24}{25}$

$Tan A = \frac{Perpendicular}{Base}=\frac{24}{7}$
