find the unknown angle measures.

A is a vertical angle to 51 and is the same.

A = 51

C is a vertical angle to 53 and is the sane. c = 53

51 + c + d need to equal 180:

51 + 53 +d = 180

d + 104 = 180

d = 180-104

d = 76

d and b are vertical angles, so b = d = 76

a = 51

b = 76

c = 53

d = 76

a 360 degree rotation

step-by-step explanation:

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°
