In triangle ABC, angle C is 90, AB = 14, angle A is 50. Find leg CB. Round the result to tenths.

To begin with, draw a triangle and mark the data that we know in the figure. Also, next to the picture, write Dano and Find.
Let’s move on to the solution: sin50 = 0.77 (approximately).
sinA = BC / AB, hence:
0.77 = BC / 14 BC = 0.77 * 14 = 10.78
Since the task says to round to tenths, the answer will be BC = 10.8
