The sum of 5 and c is greater than 25?

X2 + y 2 = 36 x + y = 6 solve the system of equations.

If chord ab is congruent to chord cd, then what must be true about ef and eg?

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
