Answer:

<h2>11.4</h2>

Solution,

∆ ACB = ∆ EFD

finding the value of X,

\frac{x}{3.8}  =  \frac{15}{5}

Apply cross product property

x \times 5 = 15 \times 3.8

Calculate the product

5x = 57

Divide both sides by 5

\frac{5x}{5}  =  \frac{57}{5}

Calculate

x = 11.4

Hope this helps...

Good luck on your assignment...

While playing baseball, sofia takes note of the extreme vectors for which she bats. what is the angle between her two extreme ba
k0ka [10]

The angle between the two extreme vectors of Sofia bats is 74.60 degrees.

In this question,

The angle between two vectors will be deferred by a single point, which is called as the shortest angle at which we have to turn around one of the vectors to the position of co-directional with another vector.

The extreme vectors of Sofia bats are  \vec u = < -8, 12 > and \vec v = < -8, 12 >

The angle between the vectors is

\theta = cos^{-1} \frac{\vec u.\vec v}{||\vec u|| ||\vec v||}

The dot product is calculated as

\vec u. \vec v = (-8)(13)+(12)(15)

⇒ -104+180

⇒ 76

The magnitude can be calculated as

||\vec u|| = \sqrt{(-8 )^{2} +(12)^{2} }

⇒ \sqrt{64+144}

⇒ \sqrt{208}

||\vec v|| = \sqrt{(13 )^{2} +(15)^{2} }

⇒ \sqrt{169+225}

⇒ \sqrt{394}

Thus the angle between the vectors is

\theta = cos^{-1} \frac{76}{(\sqrt{208} )(\sqrt{394} )}

⇒ \theta = cos^{-1} \frac{76}{\sqrt{81952} }

⇒ \theta = cos^{-1} \frac{76}{286.27 }

⇒ \theta = cos^{-1} (0.2654)

⇒ \theta=74.60

Hence we can conclude that the angle between the two extreme vectors of Sofia bats is 74.60 degrees.

The sum of two numbers is 131. One number is 6 more than 4 times the other. Which of the following is the smaller number
sertanlavr [38]

Answer: oop

Step-by-step explanation:

Let X = smaller number

Let Y = larger number

Sum of numbers is 130 ==> X + Y = 130 ==> Y = 130 - X

4 times the smaller subtracted from the larger is 10 ==>

Y - 4*X = 10

Substitute the value for Y in to the 2nd equation

(130 - X) - 4*X = 10

130 - 5*X = 10

-5*X = -120

X = 24

Y = 130 - 24 = 106

Check: 24 + 106 = 130

106 - 4*24 = 106 - 96 = 10

What is the length of the missing leg?
lbvjy [14]
A= 28.
The formula for the Pythagorean theorem is A^2 + B^2 = C^2
So plug in what you know. A^2 + 21^2 = 35^2 you get A^2+ 441 = 1225. You then take away 441 from 1225 and you get A^2 = 784. You have to find the square root of 784 which is 28. So side A is 28.
