This is the answer on Edge2020, hope this helped. :)
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°.
