Question

tan tetha=√99 find sec​

Answer 1

Step-by-step explanation:

tan(theta)=√99

tan²(theta)=99

=> since tan²(theta)=sec²(theta)-1

put value in above equation

tan²(theta)=99

sec²(theta)-1=99

sec²(theta)=100

sec(theta)=√100

sec(theta)=10

hope this will help you

Answer 2

The value of sec theta is 10

Step-by-step explanation:

given : $\tan \theta = \sqrt{99}$

we have to find the value of $\sec \theta$

using the identity $\tan^2\theta +1 = \sec^2\theta$

$\tan^2\theta +1 = \sec^2\theta\\\\(\sqrt{99})^2+1=\sec^2\theta\\\\99+1 = \sec^2\theta\\\\100= \sec^2\theta\\\\\sqrt{100}= \sec\theta\\\\\sec\theta= 10$

hence , The value of $\sec \theta$ is 10
