Find the value of YZ

Mathematics
1 answer:
ASHA 777 [7]2 years ago
5 0

Answer:

YZ = 44

Step-by-step explanation:

Let the intersection of XW and YZ equal A. For this problem, we can use power of a point in the scenario where two secants intersect in the interior of a circle. We get the equation:

WA * AX = ZA * AY

We can substitute the values we are given to get:

(2x - 6)(21) = (x + 1)(30)

42x - 126 = 30x + 30

12x - 126 = 30

12x = 156

x = 13

Using segment addition postulate, we can say that:

YZ = YA + AZ

And we can plug in what we know from the diagram:

YZ = 30 + x + 1

We can also plug in the value of x, 13

YZ = 30 + 13 + 1 = 44

A film student wants to capture a shot of a satellite dish placed at the top of a building. The line of sight between the ground
ICE Princess25 [194]

The ground, the building and the line of sight between the ground camera and the top of the building form right triangle with hypotenuse equal to 45 feet and angle adjacent to this hypotenuse and ground - 50°. The building is an opposite leg to the given angle, then you should write sine function:

\sin 50^{\circ}=\dfrac{height}{45} \\ \\ 0.766=\dfrac{height}{45}\\  \\ height=45\cdot 0.766=34.47.

The answer to the nearest tenth of a foot is 34.5 feet

N circle C, r = 32 units. What is the area of circle C?
charle [14.2K]
The answer is:  " 1024π units² " ; or;  " 3215.36 units² " .
______________________________________________________
A = π * r²  ;

A = π * 32² = 1024 π units² ;

 or, using "3.14" for "π" ;

1024 * π = 1024 * (3.14) = 3215.36 units² .
