Answer:
% change in stopping distance = 7.34 %
Step-by-step explanation:
The stooping distance is given by
![T = 2.5 x + 0.5 x^{2}](https://tex.z-dn.net/?f=T%20%3D%202.5%20x%20%2B%200.5%20x%5E%7B2%7D)
We will approximate this distance using the relation
![f (x + dx) = f (x)+ f' (x)dx](https://tex.z-dn.net/?f=f%20%28x%20%2B%20dx%29%20%3D%20f%20%28x%29%2B%20f%27%20%28x%29dx)
dx = 26 - 25 = 1
T' = 2.5 + x
Therefore
![f(x)+f'(x)dx = 2.5x+ 0.5x^{2} + 2.5 +x](https://tex.z-dn.net/?f=f%28x%29%2Bf%27%28x%29dx%20%3D%202.5x%2B%200.5x%5E%7B2%7D%20%2B%202.5%20%2Bx)
This is the stopping distance at x = 25
Put x = 25 in above equation
2.5 × (25) + 0.5×
+ 2.5 + 25 = 402.5 ft
Stopping distance at x = 25
T(25) = 2.5 × (25) + 0.5 × ![25^{2}](https://tex.z-dn.net/?f=25%5E%7B2%7D)
T(25) = 375 ft
Therefore approximate change in stopping distance = 402.5 - 375 = 27.5 ft
% change in stopping distance =
× 100
% change in stopping distance = 7.34 %

Answer:
Step-by-step explanation:
oto begin you should know that all triangles contain 180 degrees and that a flat line contains 180 degrees as well. This means that in order to find this answer you should begin by calculating the remianing angle in the traingle. This is done by 180-(95+51) and gives and angle of 34 degrees. Then take 180-(95+35) in order to get x. This gives an x of 51.
