Hey guys sorry to be a feed spammer! but i was wondering if anyone would me with this question i'm having a bit of trouble. i'll give a brainliest.

Angles ECD and ACB are vertical angles, so their measures have to be equal. Since ACB = 65 degrees, ECD also has to equal 65 degrees. Vertical angles that are angles that form an x and are always equal in measure. 

Your answer should be: 65 degrees.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
