Answer:
A one is the correct answer
The expression that represents the value of sin C - cos C is s-r
From the triangle ABC, since sin B = r and cos B = s.=, hence;
- Opposite side= r
- Adjacent side = s
- Hypotenuse = 1
If m<C is the reference angle, then;
Opposite side= s
Adjacent side = r
Hypotenuse = 1
Sin C = s and cos C = r
Hence the expression that represents the value of sin C - cos C is s-r
