Which expression can be used to determine the reference angle for an angle, x, measuring 150°?

 To find the reference angle measuring x for angle in Quadrant II the formula is:

                  180° - x = 180° - 150° = 30°

              the reference angle is 30°

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

hi there!

1. define: accuracy

a) how close a measured value is to the actual (true) value.

hope this : )
