Answer:
Denote AH as height of triangle ABC, with H lies on BC.
Applying sine theorem:
AH/AC = sin 60
=> AH = AC x sin 60 = 47 x sqrt(3)/2 = 40.7
=> Area of triangle ABC is calculated by:
A = AH x BC x (1/2) = 40.7 x 30 x (1/2) = 610.5 = ~611
=> Option C is correct.
Hope this helps!

Answer:
D
Step-by-step explanation:
Sum the three angle of triangle = 180
x + 53 + 60 = 180
x + 113 = 180
x = 180 - 113
x = 67
