Answer:
The answer is 8.88; You look at the number that comes after the second number (the second place after the decimal) and if that number is 5 or above then you round the second number up. (Sorry if it doesn't make sense, but that's the best I can explain it).
Answer:45
Step-by-step explanation:
Sin^-1= 5÷7
To start off, 50 - 2 is 48, to account for the chocolates he had left. 48 divided by 3 is 16, so Jack has 16 friends at the party!!
180 - 138 = 42°
90 + 42 = 132°
180 - 132 = 42° = m
-
90 + 42 + 2n = 180
132 + 2n = 180
- 132
2n = 48
÷ 2
n = 24°
