How would i solve this? w+4/w-9? how do i find the values for this?

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.

Ithink the answer is d.

Ithink it is 52
