You are correct with 80 on that answer. because since it is a polygon all sides add up to 180. you take 180 and subtract the number u have which is 100. u can double check your answer by looking at the angle. by looking its definitely less than 90 and not more than 90. it looks 80 to me and you can prove it by doing this 180-100=80

Answer:
206 miles/hour
Step-by-step explanation:
1 kilometre per hour = 0.621 mile per hour
332 km/hr to miles per hour
= 332 km/hr × 0.621 miles per hour
= 206.295 miles per hour
Approximately to the nearest whole number
= 206 miles per hour
1+3+5+7+...+999 =
= 1+2+3+4+...+500
+1+2+3+...+499
= 2·(1+2+3+...+499) + 500
= 2·(499·500)/2 + 500
= 499·500 + 500
= 500·(499 + 1)
= 500·500
= 250.000
