I am trying to create a question using cosine and can't figure out what I am not doing correctly.

cos[angle]*[length] is what I am trying to do where angle is a range of angles I set up and length is the side of the hypotenuse of a triangle with a range of lengths. I am solving for the adjacent side of a triangle. I'm sure it is a formatting issue but I can't figure it out. Thanks.

Hi REBECCA CLARK,

These guides may be of some use for you: How do I create a Formula quiz question with a single variable? or How do I create a Simple Formula quiz question?

I'm also not a Math Teacher, so my understanding of how this needs to be formatted may be limited. Hope this helps.
