Answer:
this is an example:
In a parallelogram, like in any other quadrilateral, the sum of the measures of the interior angles is 360 degrees. Also in a parallelogram, if you have one angle that is 65 degrees, you must also have a second angle that is 65 degrees, so the sum of those two angles is 130 degrees. The sum of the other two angles, which are of identical measure, is then 360 minus 130 equals 230 degrees. Divide 230 by 2 to get the measure of the other two angles.
Step-by-step explanation:
Multiply 75*5 to get 375
then add 120 from the lot to get 495
It has 2 variables and the other one has 1
Just set each expression equal to 3(n+6). If you get the same answer on both sides (x=x) then that expression is equivalent! :)
