Answer:
The missing measurement is 9 miles
Step-by-step explanation:
we know that
The Area of a parallelogram is equal to
where
b is the length of any base
h is the corresponding altitude
The altitude (or height) of a parallelogram is the perpendicular distance from the base to the opposite side (which may have to be extended).
In the figure, the altitude corresponding to the base is 4 miles
substitute
Solve for b
Divide by 4 both sides
therefore
The missing measurement is 9 miles

The square root of 676 was incorrect.
The square root of 676 was incorrect.
The angle based on the information given about the rail is 163°.
<h3>How to illustrate the information?</h3>From the information given, the value of angle 2 will be:
17° + x = 180° (angle on a straight line)
Collect like terms
x = 180° - 17°
x = 163°
In this case, it should be noted that angle 1 and 2 are alternate angles. Therefore, angle 1 will be 163°.
