Point D is on line segment CE.Given CD = X, DE = 7, and CE = 2x, determine the numerical length of CD
Usimov [2.4K]

Answer:

CD = 7

Step-by-step explanation:

Since D is on the line segment CE then

CE = CD + DE , substitute values

2x = x + 7 ( subtract x from both sides )

x = 7

Thus

CD = x = 7

Bo is flying a kite, holding his hands a distance of 3.5 feet above the ground and
morpeh [17]

The height of the kite will be 53.32 feet above the ground.

<h3>What is trigonometry?</h3>

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

Given that:-

  • The boy is flying a kite, holding his hands a distance of 3.5 feet above the ground and
  • letting all the kite's strings play out. He measures the angle of elevation from his hand to the kite to be 29°. If the string from the kite to his hand is 110 feet long, what is the total vertical height?

The height of the kite above the ground will be calculated as:-

Sin\theta = \dfrac{perpendicular}{Hypotenuse}

Sin(29)=\dfrac{H}{110}

H = Sin(29)  x  110

H  = 53.32 feet

The hand of the boy is 3.5 above the ground so the total height H(t) of the kite above the ground will be:-

H(t)  = 53.232  +  3.5

H(t)  = 56.28 feet.

Therefore the height of the kite will be 53.32 feet above the ground.

The third one is a point with the first equation.

I had to simplify the second equation.

It simplified to,

y =  -  \frac{1}{4} x - 2
The second one with the above is didn't go through so I'd say no solution.
