Answer:
[tex]\sin A = \frac{a}{b}[/tex]
Step-by-step explanation:
Given:
We took here a Right Angle Triangle,Δ ABC at angle B as 90°
Side opposite to angle A = a
Side opposite to angle B = b = Hypotenuse
Side opposite to angle C = c
To Find:
Sin A = ?
Solution:
Property of a Sine rule for a Right Angle Triangle.
[tex]\sin A =\frac{\textrm{side opposite to angle A}}{Hypotenuse}\\\sin A =\frac{a}{b}[/tex]
∴ [tex]\sin A = \frac{a}{b}[/tex]
