Question

Find the cosine of each acute angle

Answer 1

What is cosine?

Well, cosine is adjacent side divided by the hypotenuse.

cos M = 20/36

Reducing 20/36 to the lowest terms we get

cos M = 5/9

cos N = 30/36

Reducing 30/36 to the lowest terms we get

cos N = 5/6

Answer 2

Answer:

Cosine of angle M =

$\frac{20}{36}$

=》

$\frac{5}{9}$

Cosine of angle N =

$\frac{30}{36}$

=》

$\frac{5}{6}$

( note : cosine means cos )
