Do you have to show your calculations?
Or do you just want the answers?
>>81807
(the answers are till 3 decimal places)
11. -7.496
12. -7.272
13. -1.201
OP autistic fag, I ain't gonna solve more if you don't reply. How do I know you're even there.
>>81807
Adjacent and hypotenuse - cosine
cos(40) = 5/x
5 / cos(40) = x
x = 6.5
cmon now, trig is easy math
>>81817
opposite and hypotenuse - sine
cos(31) = x/18
cos(31) * 18 = x
x = 15.4
>>81819
opposite and adjacent - tangent
tan(25) = x/9
tan(25) * 9 = x
x = 4.2
>>81821
to find the angle "P", use sine, cosine, or tangent to find the other angle "R" and subtract it from 180
>>81823
17 and 18 are just repeating the same steps from the other problems, nothing new
(I've had lousy professors who didn't teach very much at all. It was up to everyone to pretty much learn higher math by the book. A very poorly written book, with answers in the back, but void of any useful explanation.)
