Question text what is the prime factorization of 378? select one: a. 32 x 72 b. 2 x 3 x 5 x 7 c. 2 x 33 x 7 d. 22 x 33 x 7

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
