Find the solutions of ΔKMN when m∠K = 56°, m = 19, and n = 14. Don't answer if you don't know

Answer choices

A:m∠M = 77.91°, m∠N = 46.09°, k = 16.11
B:m∠M = 102.09°, m∠N = 21.91°, k = 16.11
C:m∠M = 102.91°, m∠N = 21.91°, k = 11.51
D:m∠M = 77.91°, m∠N = 46.09°, k = 11.51

You have to find the angle i don’t know if i i try

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
