Find the missing side. Round to the nearest tenth.

If you answer 2+2 you will get over 80 points

Write two point-slope equations for the line passing through the points (6, 5) and (3, 1)

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
