Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

There will be 8 triangles made.

The center angle will be = \frac{360}{8}=45

The triangle will be formed an isosceles triangle, so remaining angle will be :

\frac{180-45}{2}=67.5

sin 67.5=\frac{opposite}{5}

opposite= CD = 5sin67.5=4.6194

Similarly,

adjacent = BD = 5cos67.5=1.9134

The complete AB will be = 2*1.9134=3.8268

Area of triangle ABC will be = \frac{1}{2}*base*height = \frac{1}{2}*3.8268*4.6194=8.838

So, the area of octagon will be 8 times area of this triangle.

Area of octagon will be = 8*8.838=70.70

Hence are the area of octagon is  70.70 :   Option D  :   Answer

Hope it will help :)

tigry1 [53]

Answer:

149°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle

<FRO + <RFO = <FOG

60° + 86 = 146

From the table, the domain are all real numbers and they can be substituted for x to return a valid f(x) value:

  • f(x) = x²
  • Domain = 2, 3, 4, 15 and x.
  • Range = 4, 9, 16, 225 and x².

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a Cartesian coordinate, which are the x-axis and y-axis.

By critically observing the table (see attachment), we can logically deduce that relationship between the amount of ink and the size of the sign is modeled by this function:

f(x) = x²

From the table, the domain are all real numbers and they can be substituted for x to return a valid f(x) value:

  • Domain = 2, 3, 4, 15 and x.
  • Range = 4, 9, 16, 225 and x².
