and so there is no remainder.
###
Quicker method: Use the polynomial remainder theorem, which says the remainder upon dividing a polynomial 
by 
is 
. Here we have
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
