Find the coordinate of the point

Question

Find the coordinate of the point on a circle with radius 3 corresponding to an angle of 113° (round to 2 decimal places).

Answer 1

3 is the hypotenuse of a right triangle with angle = 113 or 67 degrees (180-113)

the y coordinate is 3sin67 = 2.76

the x coordinate is -3cos67= -1.17

that's the point (-1.17, 2.76)
