Maria sets a goal of jogging 17.4 miles this week. She plans on running 2.75 miles each day for 7 dadys. If she follows her plan, witch is true?

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
