Question

In right triangle ABC, m B Em C. Let sin B = r and cos B = s.

Answer 1

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
