Express the following in terms of the cosine of another angle between 0 degree and 180

Question

Degree

Answer 1

To express an angle in terms of the cosine of another angle, we can use the identity:

cos(180 - x) = -cos(x)

So, if we have an angle A and we want to express it in terms of the cosine of another angle B, we can write:

cos(A) = cos(180 - B)

Therefore, A = 180 - B

So, to express an angle in terms of the cosine of another angle between 0 and 180 degrees, we can use the formula:

A = 180 - B
