The cosine of an acute angle of a right-angled triangle is the ratio of the adjacent leg to the hypotenuse.
CosA = AC / AB = 0.28.
The sine of an acute angle of a right-angled triangle is the ratio of the opposite leg to the hypotenuse.
SinB = AC / AB.
Then the cosine of one acute angle of a triangle is equal to the sine of another acute angle.
Answer: SinB = 0.28.
