Answer:
cos 90° = 0, because the angles are complements
Explanation:
Complementary angles are those angles whose angles are sum up to 90 degrees that we called right angles
Just like
one angle is 45 degrees
And, the other angles are also 45 degrees
So, the sum of both two angles are 90 degrees
Now if
sin 0° = 0
The cos 0° = 0 as the angles are considered to be the complement
We used the equation as shown below:
