Answer:
The height of the Eiffel Tower will be 318 feet.
Step-by-step explanation:
Please check the attached graph.
From the diagram, it is clear that Lizbeth is 5.5 ft tall, seeing the top from 318 feet away, making an angle of elevation to be 72⁰.
The diagram makes a right-angled triangle.
- Given the angle = Ф = 72⁰
- Hypotenuse = the height of the Eiffel Tower = c ?
Pythagorean Theorem:
For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:


 feet
 feet
Therefore, the height of the Eiffel Tower will be 318 feet.

Answer:
True 
Step-by-step explanation:
<u><em>Explanation</em></u>:-
 The equation of the standard hyperbola is  
                          
-  Hyperbola is symmetric with respective to both the axes, since if (x, y) is a point on the hyperbola, then (-x, y), (-x,-y), (x,-y) are also lie on the parabola.
- The relation of between focus and transverse and conjugate axes c²=a²+b²
-  The transverse axis is along x-axis  
-  The conjugate axis  is along y-axis
-  The length of transverse axis is 2 a
-  The length of conjugate axis is 2 b
-  The foci is (±c,0) and the equation of foci is x=±a e)
-  The length of Latus rectum is  
 
        
             
        
        
        
The expression which shows the total area of the picture and frame is  +320.
+320.
Given that the width of the frame is x ,length horizontally be 20 inches and vertically be 16 inches.
We are required to find the expression which shows the total area of the picture and frame.
Expression is basically a combination of numbers, symbols, coefficients, determinants, indeterminants,etc. and are mostly not found in equal to form.
Since we are given that the width of the frame be x, So,the are of only frame will be :
Area of frame=20*x*2+16*x*2+x*x
=40x+32x+
= +72x
+72x
Area of picture=20*16=320 
The expression which shows the total area of the picture and frame is  +320.
+320.
Hence the expression which shows the total area of the picture and frame is  +320.
+320.
