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
Therefore, the height of the Eiffel Tower will be 318 feet.
Answer:
The first term of the series is 125.
Step-by-step explanation:
The sum of the first four terms of a geometric series can be described by the following equation:

Where x1 is the first term and r is the common ratio. Replacing the given values into the equation to solve for x1 yields:

The first term of the series is 125.
1.) 0.36 ·1/2
9/25 · 1/2
9/50 or 0.18
2.) 3/7 · 2
3/7 · 2/1
3 · 2/7 ·1
6/7 or 0.857142
Answer:
A = 21
Step-by-step explanation:
Hello
The triangle area is= (base*height)/2, so
A = (6*7)/2
A = 42/2
A = 21
Remember that a trinagle is the area of half square =D
