Answer:
65 degrees
Explanation:
m<3 and m<5 are vertical angles.
Based on the vertical angles theorem,
m<3 is congruent to m<5.
Therefore, if m<5 is given as 65°, thus:
m<3 = 65°
How long was each sprinkler used is 30 hours.
<h3>How long was each sprinkler used </h3>
Let x represent how long each sprinkler was used
Hence:
40(x)+15(55-x)=1575
40x+825-15x=1575
Collect like terms
40x+-15x=1575-825
25x=750
Divide both side by 25x
x=750/25
x=30 hours
Therefore the Jenkins used the sprinklers for 30 hours while Green's used it for 25.
