b.

Answer to Problem 36PPE
The given pair of angles are complementary angles for which sine of given angle is equal to complementary of cosine of other angle.
Explanation of Solution
Given information: The given trigonometric expressions are,
Calculation: From (2) it is observed that,
It means that the given pair of angles are complementary angles for which sine of given angle is equal to complementary of cosine of other angle.
c.
Explain why the result make the sense.
c.

Answer to Problem 36PPE
The result makes the sense which means the given angles are complementary.
Explanation of Solution
Given information: The given trigonometric expressions are,
Calculation: From (2) it is observed that,
Therefore the statement (2) is correct and the result makes the sense which means the given angles are complementary. And for complementary angles formula
