Question

for an assignment I have to find the answer of 23 divided by cos(9) and when I put it into the calculator I get -25.24 which is wrong. Is there anyway I can do this without a calculator?

Answer 1

To divide 23 by Cos(9), you would definitely need to use the calculator.

If the calculator is in radians mode, you would get one answer and in degrees mode, you will get another answer.

In radian mode:

`(23)/(\cos 9)=-25.24`

In degree mode:

`(23)/(\cos 9)=23.29`
