Two sides of a right triangle measure 2 units and 4 units.

wel

Answer:

Step-by-step explanation:

using pythagorean theorem to find the hypotenuse gives √20, so the measure of the side of the square is also √20, square that to give the area of square, which is 20

What does p equal in the equation?

Nutka1998 [239]

Time the -2 to p and -5 to get -2p+10+7p=-5
subtract the ten from both side getting -2p+7p=-15
if you add -2 to 7 it would be 5 getting 5p=-15
then you divide 5 from both sides getting p= -3
p =-3 is the correct answer

A girl is flying a kite with a 120ft string attached to the ground is flying directly Selena’s head is standing 24 ft from where

SashulF [63]

Answer:

111.58 feet

Step-by-step explanation:

Given that the length of the string (AB in the attached diagram) is 120 feet.

Selena (at point D) is standing 24 feet from point A, where the kite is attached to the ground.

Since the kite is directly above Selena's head, the problem forms a right triangle.

Using Pythagoras theorem

$|AB|^2=|BD|^2+|AD|^2\\120^2=|BD|^2+24^2\\|BD|^2=120^2-24^2\\|BD|^2=13824\\|BD|=\sqrt{13824} \\|BD|=117.58$ ft$

Serena's height (CD=6 feet)

The distance of the kite above her head is BC in the drawn diagram.

Therefore:

|BD|=|BC|+|CD|

117.58=|BC|+6

|BC|=117.58-6

|BC|=111.58 feet

The kite is approximately 111.58 feet above Selena's head/
