<h3>
Answer: 9</h3>
========================================================
Work Shown:
Apply the pythagorean theorem
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 225-144
b^2 = 81
b = sqrt(81)
b = 9
First day: 25% × 100 = 25 ( miles)
Second day : the remaining distance is 100 - 25 = 75 ( milesl
Third day: 40% × 75 = 30
25 + 75 + 30 = 130 (miles)
The dimension of the parallelogram ABCD will be 14 inches, 48 inches, 14 inches and 48 inches.
<h3>What is a parallelogram?</h3>
It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
The perimeter of a parallelogram is 76 inches.0
And one side measure is 14 inches.
Then the rest of the sides will be
We know that opposite sides are prallel and equal.
Let ABCD is a parallelogram.
AB = CD = 14 inches
BC = AD = x
Then the value of x will be
We know
P = 2(AB + BC)
76 = 2(14 + x)
x = 48
