Question

B In right triangle ABC, m_B+ m_C Let sin B = x and cos B =y. What is sin C- cos CP

Answer 1

y - x

Step-by-step explanation:

In the right triangle ABC, we have the following relationships:

sin B = cos C

cos B = sin C

So, to know what is sin C - cos C, we replace the expression as:

sin C - cos C = cos B - sin B

Then, taking into account that sin B = x, and cos B = y, we get:

sin C - cos C = y - x

Therefore, the answer is y - x
