The sum of two consecutive integers is at least 36.

what is the least possible pair of integers?

a: 17 and 18

b: 18 and 19

c: 19 and 20

d: 16 and 17

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
