Answer:
65 degrees
Step-by-step explanation:
85 + 30 = 115
180 - 115 = 65
Verify:
a + b + c = 180
85 + 30 + 65 = 180
180 = 180
81. a negative times a negative is a positive
7:45-5:51 gives you the difference in times remember 60sec per min (1:54)
turn it into only seconds so 60+54=114s and 7x60+45=645s
114/645 gives you the percentage of difference
