a.
To write equation to find the length of the skid marks.
a.
Answer to Problem 1MP
Explanation of Solution
Given information :
Here we shall use the Pythagoras theorem.
According to Pythagoras theorem in any right angle
Hence we shall put the values given,
Let the length of the skid marks be
Hence this is the equation to determine the length of skid marks.
b.
To find the length of the skid marks.
b.
Answer to Problem 1MP
The length of skid marks is 140 ft.
Explanation of Solution
Given information :
Here we shall use the Pythagoras theorem.
According to Pythagoras theorem in any right angle triangle,
Hence we shall put the values given,
Let the length of the skid marks be
Hence the length of skid marks is 140 ft.
c.
To explain how out answer in part b is reasonable.
c.
Explanation of Solution
The length of skid marks is 140 ft.
This length of the right angle triangle is the leg of the triangle and hence we be shorter than the hypotenuse. As we know that the hypotenuse is the largest side in a right angle triangle.
This answer is reasonable as it can be clearly observed that it is shorter than the length of hypotenuses.
