Answer:

m∠L + m∠M = 90°

sin(L) = 0.66913

sin(M) = 0.74314

Step-by-step explanation:

The sum of the two angles is ...

 m∠L + m∠M = 42° +48° = 90°

__

A calculator can show you the sines of these angles.

 sin(42°) ≈ 0.66913

 sin(48°) ≈ 0.74314

_____

The two acute angles of a right triangle always have a sum of 90°.

Answer:

its all true

Step-by-step explanation:

A B C D are true

Which statements are true about the ordered pair (−4, 0) and the system of equations?

{2x+y=−8
{x−y=−4


Select ALL correct answers.


The ordered pair (−4, 0) is a solution to the first equation because it makes the first equation true.

The ordered pair (−4, 0) is a solution to the second equation because it makes the second equation true.

The ordered pair (−4, 0) is a solution to the system because it makes both equations true.

The ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false.
