To convert an angle from degrees to radians, multiply by π/180°.
Your angle is
(-280°)*(π/180°) = -14π/9
The appropriate choice is ...
B) (-14π/9)
The calculation is not reasonable, because 0.45 is less tha 1/2 ( 0.50) and what he has for an answer is half the distance ( 250.17 is 1/2 of 500.34).
To find actual mileage, multiply by 0.45:
500.34 x 0.45 = 225.153 miles.
Round the answer as needed.
200/5 = 40...she should read at least 40 per day to reach her goal
The product of 68 and 21 would be 1,428.
If you graph 4 separate triangles with the four different points, (2,3) and (1,5) form a right triangle.
