Evaluate (sin45 degrees)(cos30 degrees) / sec45 degrees
a)5
b)7/3
c)1/2
d)7/2
My best guess is 1/2 but I'm not sure if I did the problem right. I found sin 45 and cos 30 multiplied the vvalues together and then divided them by sec45. My answer was 0.5303295 and I rounded that off to 1/2.
Please help.
I gave the wrong answers!
The correct answers are
a)1/4
b)sqrt3/4
c)sqrt3/2
d)sqrt3
Now 1/2 isn't even an option so now I know I did it wrong.
Put (sin45 degrees)(cos30 degrees) / sec(45 degrees)
into the Google search engine. That elminates a, d, c...all of those have to be greater than one.
