Question

The given angle is approximate. Find the value of the given trigonometric function by finding the reference angle and attaching the proper sign.sec 495.58 degrees (Round two decimal places

Answer 1

- sec 44.42

Step-by-step explanation:

First, let us subtract 360° from 495.58°. This gives

`495.58^o-360^o=135.58^o`

The reference angle is the angle that is an acute angle between the terminal side and the x-axis.

As can be seen in the above figure, the reference angle is given by

`180^o-135.58^o=44.42^o`

Hence,

`\boxed{\sec495.58^o=-\sec44.42^o}`
