When the robot makes a turn, it would be useful to have an operation to perform on d to represent this turn. this is because after making a turn, the new value of d will depend on the old value of d. complete the table for the new values of d if the robot is turning left or right. then determine an expression in terms of d that will give the new position if the robot turns left and another expression if the robot turns right. type these expressions in the last row of the table.
the answer is a
because if you put 1 in to the square root of x it equals 300.
d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
