Answer 1

Hey! I The correct answer is option A for plato users, i just took the test

Explanation:

A.
`(19)/(20)`

Answer 2

ANSWERS

A.

`(19)/(20)`

EXPLANATION

It was given that triangle LMN is a right triangle and angle L and M are complementary.

This implies that:

`\sin(L) = \cos(M)`

It was given in the question that:

`\cos(M) = (19)/(20)`

This implies that:

`\sin(L) = (19)/(20)`
