Find the measure of angle deg. image of five-sided polygon abcde with a ray extending out of each corner; the angles formed in corners a, b, c, and d are labeled 115 degrees, 52 degrees, 88 degrees, and 61 degrees respectively; the fifth corner forms angle deg 65° 44° 105° 72°

ANSWER



EXPLANATION

The sum of the exterior angles of a polygon is


So we sum all the exterior angles to obtain,



This implies that,



We group like terms to obtain,



This simplifies to,



Therefore the correct answer is option B.

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
