Answer:6 events
Step-by-step explanation:
13505+ 18.5x =13616
round too? hundreds? thousand? ones? where do we round too? i need to know so i can help you :)
The labeled angle is what's called an inscribed angle. There's a theorem (fittingly called the inscribed angle theorem) that says the measure of this angle is half the measure of the circular arc that it subtends.
In this case, the angle is subtended by an arc measuring 180°. So
(4x + 6)° = 1/2 • 180°
4x + 6 = 90
4x = 84
x = 21
