Answer #1

Given point is ( 2.02,1.1) =

from the figure, we can see that the radius of the circle is 2 .3 units. so r=2.3

so       and

Multiplying and dividing with 2.3

A toy racecar races along a circular track. The racecar starts at the 6-o'clock position and travels in the CCW direction, and is always 4.5 feet from the center of the race track. Imagine an angle with an initial ray pointing in the 6 o'clock direction and with a terminal ray passing through the racecar. (Draw a diagram of this!) Let θθ represent the angle's measure. Write an expression (in terms of θθ) that represents the measure of the angle...
