The variable that you would have to plot on the y axis (height) is the dependent variable while the variable that is on the x axis (arm span) is the independent or the explanatory variable.
<h3>How to get the slope of the line</h3>
The slope was gotten through the use of the points (37,39) and (19,25)
This gave the slope of 7/9. This tells us that height of the person got to be raised by 7/9 inches when arm span increases by 1 inch.
From the given model, a person that has the arm span of 66 would have the height of
12 + 7/9 * 66
= 63.3 inches
A person who is 74 inches height the arm span of = 62*9/7
= 79. 71 inches.

Angle ABD=87 degrees
angle ABC+angle CBD= angle ABD
Therefore, 9x-1+6x+58=87
15x+57=87
15x=87-57
15x=30
x=30/15
x=2
Angle ABC= 9x-1
=9(2)-1
=18-1
=17 degrees
Answer:
438
Step-by-step explanation:
subtract 76 from 256 you get 180 then add 180 to 256
180=36+2x +x
180=36+3x
144=3x
Divide both side of equal sign by 3 to get variable by itself.
48=x
Then subtract 48 from 180 =132
So angles are 48; 132
I would go with G or J...
