Answer:
angle plm+angle lpm+angle pml=180°[by angle sum property]
21°+angle lpm+38°=180°
59°+ lpm=180°
lpm=180°-59°
lpm=121°
lpm+npl=180°[by limear pair]
121°+npl=180°
npl=180°-121°
npl=59°
Amber coaches both sports for 7 hours each day
v = volleyball hours
s = soccerball hours
7 hours in total, in which soccerball is 1 hour more than volleyball:
v + s = 7
s = v + 1
plug in v + 1 for s
v + s = 7
v + (v + 1) = 7
simplify
v + v + 1 = 7
2v + 1 = 7
2v + 1 (-1) = 7 (-1)
2v = 6
2v/2 = 6/2
v = 6/2
v = 3
Plug in 3 for v for one of the equations.
s = v + 1
s = (3) + 1
s = 4
Amber coaches 3 hours for volleyball, and 4 hours for soccer, making a total of 7 hours
hope this helps
