C. sin 79degrees 23'30'

**helper**, Friday, January 14, 2011 at 12:10ammy trig book has tables in degrees and minutes

for example, look-up sin 24 deg 40 min and sin 24 deg 50 min. cal. the correction and add to the smaller angle for sin, tan, sec (subtract the correction for cos, cot, csc)

sin 24d 40' = .4173

sin 24d 50' = .4200

difference = .0027

actual minutes = 43'

smaller angle above = 40'

difference = 3' * .10 = .3000

correction = .3000 * .0027 = .0008

sin 24d 40' = .4173

add correction .0008

sin 24d 43' = .4181

you try the others
