there is an acronym for this: soh-cah-toa
soh: sine is opposite over hypotenuse
cah: cosine is adjacent over hypotenuse
toa: tangent is opposite over adjacent
The solutions are x=5,-1<span />
Answer:c=34.2
Step-by-step explanation:
c = 2πr;
π = 3.142;
r=5;
c=2(3.142)5
c=34.2
X=1119/2 hope this helps :)
0.133 because 5 mean you have to round up so it is 0.133
