If right triangle lmn, l and m are complementary angles and sin (l) is 19/20 what is cos (m)

Value of cos(M) is

Step-by-step explanation:

Since we have given that

LMN is a right angled triangle where L and M are complementary angles ,

And,

so, we will find base now by using "Pythagorus theorem":

As we know that side opposite to mentioned theta is considered as perpendicular as shown in the figure ,

For M as

NL will be its perpendicular and MN will be its base and to find the cos(M) we use Base and Hypotenuse.

So, now we will find cos(M) i.e.

Hence,

there still no table
