What's the answer to this pls I'll give brainliest ​

Write the fraction or mixed number and the decimal shown by the model

Ineed with math stuff it involves graphs

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
