43.1 degrees (choice B)
Work Shown:
Use the law of sines
sin(A)/a = sin(C)/c
sin(A)/20 = sin(82)/29
sin(A) = 20*sin(82)/29
sin(A) = 0.68294349
A = arcsin(0.68294349)
A = 43.074088
A = 43.1 degrees
10/60
step-by-step explanation:
if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
