Step-by-step explanation:

Answer:


Last choice is correct.


Step-by-step explanation:


Given that ∠C=90°, ∠B=30°, c=10


We know that sum of all angles in a triangle is 180 degree.


∠A+∠B+∠C=180°


∠A+∠30°+∠90°=180°


∠A+∠120°=180°


∠A=60°


Now we can use sin or cos whichever applicable to find missing sides


2b=10


b=5


Similarly


a=8.6602


Hence last choice is correct.
