Gabriel is 16 years older than sam. in 4 years, gabriel will be twice as old as sam. what is gabriel's age now?

        Today                               In 4 years

Gabriel (G): S + 16                   (S + 16) + 4  = S + 20

Sam (S): S                                 (S) + 4 = S + 4

S + 20 = 2(S + 4)

S + 20 = 2S + 8

     20 = 2S + 8

      12 = 2S

      6 = S

Gabriel (G): S + 16  = (6) + 16  = 22

Gabriel=22 yrs

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

6e14 is the answer.
