Question

Write the complementary angel for the cosine that makes the equation equal

Answer 1

SOLUTION

Step 1 :

In this question, we are meant to use the calculator to check if the sine of the angle is correct.

Step 2 :

Using the complimentary property of sine and cosine, we have the following equations:

$\sin \text{ }\theta\text{ = cos ( 90 - }\theta\text{ )}$$\sin \text{ ( 57 ) = cos ( 90 - 57 ) = cos ( 33)}$

CONCLUSION:

$\sin \text{ ( 57 ) = cos ( 33 )}$
