Ineed with this problem if someone could be of assistance

1) cos 105°

2) tan 67.5°

3) sin 67.5°

4) tan 165°

Step-by-step explanation:

From half angle identity

For sin 67.5 = sin (135/2)

Here 67.5° lies in Ist quadrant therefore

For cos 105 = cos (210/2)

From half angle identity

Since cos 105 lies in second quadrant

Therefore

For tan165 = tan (330/2)

From half angle identity

For tan 67.5 = tan (135/2)

From half angle identity

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

265 words per minute

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

    200 words per minute

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
