Hello,
Answer B
An exterior angle of a circle has like measure the half of difference of the arcs.
mes S=(85°-25°)/2=60°/2=30°
1. -10v(v^3 + 6v^2 + 7)
2. 4m^2(3m^3 + 9m + 10)
3. 10(n^2 + 5n - 8)
4. 42^3= 70488/18= 4166
42^2= 1764/18= 98
-18(x^4 + 4166 - 98)
A is equal to 1100 miles
B is equal to 3300 miles
You take 1650 and divide by 3 which is 550, that is 1 hour is equal to 550 miles.
It is 45 because angle EBC is congruent to CDE (x) because of a rule called alternate angles. so x= 45°
