Application +4 | -1
The perimeter of a Δ  ABC\Delta \;ABC is 6 times the arithmetic mean of the sine ratios of its angles. If a=1a = 1, then AA is equal to
View answer and explanation
Correct option: A
π6\frac{\pi }{6}
Option A (π6\frac{\pi }{6}) is correct because by using the given condition and the sine rule, we find that angle A is π6\frac{\pi }{6}.
