In the right triangle LMN, L and M are complementary angles and sin(L) is 19/20. What is cos(M)?

Solution:

It is given that,

sin (L) = 19/20.

As we know that the sine of angle L is equal to the cosine of L's complement from our rule, which is M.

This means that the cosine of M is equal to 19/20.

Therefore, cos(M) is 19/20.

In the right triangle LMN, L and M are complementary angles and sin(L) is 19/20. What is cos(M)?

Summary:

The right triangle LMN, L and M are complementary angles and sin(L) is 19/20. cos(M) is 19/20.
