In triangle ABC, angle C is 90 degrees, sine B is 7/25. Find AC.

The sine of an angle in a right-angled triangle is the ratio of the opposite leg to the hypotenuse. In triangle ABC opposite angle B lies leg AC, AB – hypotenuse. Then sinB = AC / AB = 7/25, therefore AC = 7 conventional units.
Answer: AC = 7 conventional units.
