Do you have to show your calculations?
Or do you just want the answers?

(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.

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

Ty for this, it's helping me learn how to do it and it gets me the answer so I can double check

>>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.)
