Answer:
Step-by-step explanation:
1) First, find the slope by using the slope formula, 
. We can see that the two points marked on the line are (0, -3) and (3,0). So, substitute the x and y values of those points into the formula and solve:
So, the slope is 1.
2) Slope-intercept form is represented by the formula 
. Substitute values for 
and 
in order to write an equation.
Substitute 1 for since it represents the slope. Substitute -3 for since it represents the y-intercept. (Remember that the y-intercept is the point at which the line intersects the y-axis. So, by looking at the graph provided, we can see that (0,-3) is the y-intercept without doing any calculations.) This gives the following answer:
There are 4 triangles, all in all.
The total interior angle is 180.
180 = 69 + 43 + (1)
(1) = 180 - 69 - 43
(1) = 68
180 = 112 + 41 + (2)
(2) = 180 - 112 - 41
(2) = 27
180 = 66 + 44 + (3)
(3) = 180 - 66 - 44
(3) = 70
180 = 109 + 29 - (4)
(4) = 180 - 109 - 29
(4) = 72
10 times .05 is 10.50 so $10.50
15.20 would be the tip
Hope this helps :)
