Question

If the cos 23° = two thirds, then the sin 67° = _____. two thirds, because the angles are complementary one half, because the angles are complementary three halves, because the angles are supplementary 1, because the angles are complementary

Answer 1

Answer:

  two thirds, because the angles are complementary

Step-by-step explanation:

The cosine of an angle is equal to the sine of its complement.

  cos(23°) = 2/3 = sin(67°)

Answer 2

The cos23° = 2/3 = sin67° because the angles are complementary If the cos 23° = two thirds.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have given:

cos23° = 2/3

The above expression can be written as:

cos(90-67) = sin67°    (cos(90-θ) = sinθ)

Thus, the cos23° = 2/3 = sin67° because the angles are complementary If the cos 23° = two thirds.
