<h3>Answer: 110 square miles</h3>
=============================================================
Explanation:
There are a few ways to do this.
One method involves drawing a horizontal line to form three rectangles as show below. Note the labels A,B,C.
- Rectangle A in the upper left corner has area of base*height = 6*7 = 42 square miles. I'll let A = 42 since we'll use it later.
- Rectangle B is 20 miles across horizontally (base) and 2 miles tall vertically (height). The 2 miles is from 9-7 = 2. The area of rectangle B is 20*2 = 40 square miles. Let B = 40.
- Then finally, C = 28 because rectangle C is 4 miles across and 7 miles tall, so 4*7 = 28.
Add up those three sub areas found: A+B+C = 42+40+28 = 110 square miles
----------------
There are other methods you could do. A second method is to draw two vertical lines to form 3 other rectangles, then add up the sub areas to get 110.
A third method is to draw a horizontal line across the top to form one large rectangle (20 mi by 9 mi) and subtract off the area of the 7 mi by 10 mi inner rectangle (the empty space), so you'd say 20*9 - 7*10 = 180-70 = 110
Answer:
A. 4".
B. Approximately 9.54".
C. Approximately 13.54".
Step-by-step explanation:
Please find the attachment.
Let x be the distance from the peak of the kite to the intersection of the diagonals and y be the distance from the peak of the kite to the intersection of the diagonals.
We have been given that two sides of a kite are 10 inches and two sides are 5 inches. The shorter diagonal is 6 inches.
A. Since we know that the diagonals of a kite are perpendicular and one diagonal (the main diagonal) is the perpendicular bisector of the shorter diagonal.
We can see from our attachment that point O is the intersection of both diagonals. In triangle AOD the side length AD will be hypotenuse and side length DO will be one leg.
We can find the value of x using Pythagorean theorem as:
Upon taking square root of both sides of our equation we will get,
Since distance can not be negative, therefore, the distance from the peak of the kite to the intersection of the diagonals is 4 inches.
B. We can see from our attachment that point O is the intersection of both diagonals. In triangle DOC the side length DC will be hypotenuse and side length DO will be one leg.
We can find the value of y using Pythagorean theorem as:
Upon substituting our given values we will get,
Upon taking square root of both sides of our equation we will get,
Since distance can not be negative, therefore, the distance from intersection of the diagonals to the top of the tail is approximately 9.54 inches.
C. We can see from our diagram that the length of longer diagram will be the sum of x and y.
Therefore, the length of longer diagonal is approximately 13.54 inches.
