Find missing angle !.

Step-by-step explanation:

We can use a couple of angle relationships to find the missing angle.

1. All angles in a triangle add up to 180°

We know that all angle in a triangle will add up to 180°. Since we know the measure of 2, we can find the other angle easily.

So the other angle in the triangle is 50°.

2. The 50° angle and the missing angle are supplementary.

We know that the missing angle and the third triangle angle are supplementary. This means that their angle measures will add up to 180°.

Since we know one, we can find the measure of the other.

So the missing angle is 130°.

Hope this helped!

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.
