5/6 is equivalent to 10/12
hope this : )
for -12 and -5, it is 7. for -12 and -7 it is 5
hope this ! brainliest appreciated!
hello from mrbilldoesmath!
the attachment shows a right triangle where arcsin(@) = 1/4. (the arcsin means find the angle whose sine is 1/4 as is done in the triangle.) the missing side, sqrt(15), shown in red, was determined by the pythagorean theorem.
then cos(@) = cos(arcsin(1/4)) = sqrt(15)/4
