Answer:
Sin A = 1/2 means taking the inverse of Sin which is arcsin and then solving for A.
Do the same thing for Cos A = 1/2. The inverse of Cos is arccos and then solve for A.
The answer is pi/3. Knowing the unit circle helps too.
Good luck!
If sin A is 1/2. Then the value of cos A will be √3 / 2.
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
If sin A is 1/2. Then the value of cos A will be
We know that
sin² A + cos² A = 1
Then we have
(1/2)² + cos²A = 1
cos² A = 1 - 1/4
cos² A = 3/4
cos A = √(3/4)
cos A = √3 / 2
