Fill out the chart. I don’t understand.

Negative 5 1/12 + negative 4 1/4 + 6 3/4

Consider circle o, where and . m∠bpd °. °.

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
