B) 0.28
arcsin(.28)=x
x=16.3
cos(90-16.3) = 0.28
Complement of an alngle means what you need to add to it to make 90 degrees
comlement of angle x is y such that x+y=90
so if complement of angle x is 25, that means the angle x is found by
x+25=90
minus 25 both sides
x=65 degrees
the angle measures 65 degree
I'm not to sure but i'm pretty sure the substitution method is the way to solve this
<u><em>Answer: the answer is 10! B)X=10 </em></u>
