Question

If theta is a complementary angle then sec theta is equal to

Answer 1

Step-by-step explanation:

astheta is complementary

sec 90 is not defined

Answer 2

$sec\theta=cosec\phi$

Step-by-step explanation:

Given: $\theta$ is a complementary angle.

We know that

Complementary angle: The two  angles whose sum is equal to 90 degrees.

If $\theta$ is a complementary angle then its complment is $90-\theta$ .

We know that

$Sec(90-\theta)=cosec\theta$

$Cosec(90-\theta)=Sec\theta$

By using the property

Then, we get

$sec\theta=cosec(90-\theta)$

Suppose $90-\theta=\phi$

Then, $sec\theta=cosec\phi$
