Question 839428: Points on the terminal sides of angles play an important part in the design of arms for robots. Suppose a robot has a straight arm 10 inches long that can rotate about the origin in a coordinate plane. If the robot's hand is located at (10, 0) and then rotates through an angle of −150°,what is the new location of the hand? (Round your answers to two decimal places.)
(x,y)=( )

You can put this solution on YOUR website! Points on the terminal sides of angles play an important part in the design of arms for robots. Suppose a robot has a straight arm 10 inches long that can rotate about the origin in a coordinate plane. If the robot's hand is located at (10, 0) and then rotates through an angle of −150°,what is the new location of the hand? (Round your answers to two decimal places.)
------
x = 10 + 10cos(-150) = 10-8.66 = 1.34
y = 0 + 10sin(-150) = -5
--------------------------------
(x,y)=(1.34,-5)
