Step-by-step explanation:
Objective: Understand trigonometric relations such that
Cosine and Sine are similar to complementary angles that if X+Y are complementary angles,
Cos X= Sin Y and Cos Y= Sin X
Answer:
X= 18; Y=15
Step-by-step explanation:
As a student myself working this out I cannot explain how I got the answer but I know it is correct.
<u>-5a²+13ab</u> should be subtracted.
