Asighting from sea level to the top of a lighthouse was 60°. the lighthouse is known to rise 180 feet above sea level. what is the distance (to the nearest foot) between the observer and the base of the lighthouse?
can someone explain this one for me?

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
