In right triangle LMN, L and M are complementary angles and sin(L) is 19/20. What is cos(M).
A. 19/20
B.
C. 1/20
D.

Option A:

Solution:

The image of the triangle is attached below.

Given data:

Using trigonometric ratio formulas,

So, MN = 19 and LM = 20

Using Pythagoras theorem,

In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.

Subtract 361 from both sides,

39 = LN²

Taking square root on both sides,

Hence option A is the correct answer.
