If ab and cd are congruent what is the measure of

The graph of the quadratic function shown on the left is y = –0.7(x + 3)(x – 4). the roots, or zeros, of the function are . determine the solutions to the related equation 0 = –0.7(x + 3)(x – 4). the solutions to the equation are x =

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
