True or false? it's not possible to build a triangle with side lengths of 3 3 and 9

35 points, ! name one pair of congruent sides. a. segments pr and sv b. segments qr and st c. segments rp and ts d. segments pq and vs

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

Consider the sequence below. 3 , 1 , 1/3 , 1/9 , select the explicit function which defines the sequence.
