In ∆ ABC, ∠B = 90°, AB = 8 cm and BC = 15 cm, then sinC = ?

1. 15
  17
2. 8
  17
3. 15
  8
4. 8
  15

Correct Option: B

On the basis of question we draw a figure of triangle ABC ,

Given that , ∠B = 90°, AB = 8 cm and BC = 15 cm
∴ AC = √AB² + BC²
AC = √8² + 15²
AC = √64 + 225
AC = √289 = 17 cm.

∴ sin c =	AB	=	8
	AC		17
