Hint: The total of angle measurements inside any pentagon is the same.
Hint: Look up the mathematical definition of an arithmetic sequence.
IF THE MEASURES OF THE ANGLES OF A PENTAGON FORM AN ARITHMETIC SEQUENCE, WHAT ARE THE GREATEST AND LEAST MEASURES EACH ANGLE CAN HAVE?
There is no unique answer to this question, the following 3 sets are just some examples of solutions
each set forms an arithmetic sequence and adds up to 540º
Was there an additional piece of information that you skipped?
