Question

this is exactly how the question is written and i tried to solve it but i just couldn't. Can u please show me how the work was done I don't want just the answer.

using the exact values,find the value of:

12 sin 30degrees - 6 tan of 45 degress + sec 45 degrees / 52.

please help!

Answer 1

12 sin 30degrees - 6 tan of 45 degress + sec 45 degrees / 52.
sin 30 = 1/2
tan 45 = 1
sec 45 = sqrt(2)

12 * 1/2 - 6 * 1 + sqrt(2)/52
12/2 - 6 + sqrt(2)/52
6 - 6 + sqrt(2)/52
0 + sqrt(2)/52 = sqrt(2)/52
