Okay...so, these are my example problems for this section. Section Level Video: Section 7.5 This is literally the same series of problems I have in my book. I have no other material teaching me in this section.
And here's the problem I have from this section:
"A crate is supported by two ropes. Rope 1 makes an angle of 46 degrees 23 minutes with the horizontal and has a tension of 98.4 pounds on it. Rope 2 is horizontal. Find the weight of the crate and the tension in the horizontal rope."
From what I can tell, this is not an application of the law of sines or cosines. How do I solve this?
