If sin m = cos n and m n= 30°, what is the measure of m?

step-by-step explanation:

cos(30) = 0.866

sin(60) = the same thing.

rule cos(n) = sin(90 - n)

so if you find cos 50 and sin(40) they should be the same thing.

if you take sin(50) and cos(40) , they should be the same thing.

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
