Hey I need an answer ASAP, please Point Z (-2, -7) is a reflection across the x-axis. What was the starting point?

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

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
