Assoli18 [71]

Answer:

The answer is below

Explanation:

A kite is a quadrilateral (has four sides and four angles) with two pairs of congruent adjacent sides.

From the image we can see that one pair of congruent side has be formed with a length of 30 feet. Therefore the amount of rope that has been used is 60 feet and 40 feet (100 - 60) of rope would be remaining to complete the kite. Hence 40 feet of rope would be used to make the other pair of adjacent side.

This means that the remaining pair of adjacent side would be 20 feet each so that all the roe would be used.

Adam, who is 5'6" tall, notices his shadow on the sidewalk. If the angle of elevation from the tip of the shadow to the sun is 6
german
<h2>Answer:</h2>

This problem can be solved using trigonomtry, assuming that the figure formed by Adam's shadow and Adam himself is a Right Triangle (as shown in the figure attached).


According to this,  the distance from the tip of the shadow to the top of Adam's head is the hypotenuse H of the triangle, and we already know Adam's height and the angle of elevation. So, the trigonometric function that best works in this case is sine:


sen(angle)=\frac{Oppositeleg}{hypotenuse}  


Where the opposite leg is the side of the triangle that is opposite to the 60\º angle.

In this especific case:


sen(60\º)=\frac{5.6feet}{H}     (1)


In order to know the value of the hypotenuse we have to find  H from equation (1):

H=\frac{5.6feet}{sen(60\º)}



H=6.4663 feet



Rounding:

H=6.46 feet>>>>>This is the distance from the tip of the shadow to the top of Adam's head
