Use the figure for Exercises 13-15. Find the measure of the given angle. 112°
430
33°
1710
b
15. C
13. a
14. b

a + 112 + 33 = 180 ( sum of interior angles of tria

or a + 145 = 180 - ngle is 180 degrees)

or a = 180 - 145

or a = 35 .

similarily,

c + 43 + 71 = 180

or c + 114 = 180

or c = 180 - 114

or c = 66 .

and ,

a + 71 + b = 180 ( sum of angles in straight line is or, 35 +71 + b = 180 180 degrees)

or , b + 106 = 180

or, b = 180 - 106

or, b = 74 .

Thank me later.

what are the answear choices to the question.

step-by-step explanation:

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
