Based on the information given you create an image to guide you best. From there you need to remember that the reference angle is given (which is 40) since the length opposite to this angle is given (65 in height of Jessica) the length of the shadow is needed or the length adjacent to this angle. Therefore the rule of tangent is used and once all calculations are completed you get that the length of the shadow is 77 inches.

Answer:
Inverse operations are operations that are opposite or “undo” each other. For example, addition undoes subtraction and division undoes multiplication.
Step-by-step explanation:
40-25=15l conspumtion in 150km
average=150/15=10km/l
distance in 25l=10X25=250
