4in x 18in^2= 72 inches cubed
Answer:
No
Step-by-step explanation:
An irrational number is a number that never ends or repeats. This decimal ends and it doesn't repeat.
The horizontal distance is given by the formula:
tan θ=opposite/adjacent
where:
θ=21
opposite=2000 ft
adjacent=a
thus calculating for a we get:
tan 21=2000/a
thus
a=2000/tan 21
a=5210.18 ft
Answer: 5210.18 ft
