In triangle ABC, angle C is 90 degrees, AC = 9, AB = 25. Find sin B
| September 14, 2021 | education
If angle C is straight, then the side of triangle AB is the hypotenuse, and the leg AC is located opposite the angle B.
In a right-angled triangle ABC, the ratio of the leg AC to the hypotenuse AB will be equal to the sine of angle B:
sin B = AC / AB = 9/25 = 0.36.
Answer: sin B = 0.36.
