Examine the diagram, what is the measure of angle 1?

71

Step-by-step explanation:

We can find the value of x

63 + 15x -3 = 180 since they from a straight line

Combine like terms

60 +15x = 180

Subtract 60 from each side

60-60+15x = 180-60

15x =120

Divide each side by 15

15x/15 = 120/15

x =8

We know that <1 = 8x+7  since they are vertical angles

                            = 8(8) +7

                            =71

the answer is 71

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
