The answer to your question is Ф = 210°; sin 120 = -1/2

Step-by-step explanation:

Data

Ф = 7π/6

∠ = ?

sin Ф = ?

Process

1.- Convert radians to degrees using proportions and cross multiplication

                     π rad     180°

                   7π/6 rad     x

                     x = (7π/6 x 180) / π rad

                     x = (7 x 180) / 6

                     x = 1260/6

                     x = 210°

2.- Find the sin of 210°

sin 210 = -1/2

step-by-step explanation:

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
