We can Notice From the Figure that the Sides of the Triangle are Equal.
If a Triangle has all of its Sides Equal, then it is an Equilateral Triangle
We know that In an Equilateral Triangle all Angles are Equal to 60°
⇒ (2x - 4) = 60°
⇒ 2x = 60° + 4°
⇒ 2x = 64°
⇒ x = 32°
Answer:
A. is correct

Answer:
<h2>C ≈ 12.56 m, A ≈ 12.56 m²</h2>
Step-by-step explanation:
The formula of a perimeter (circumference) of a circle:

<em>d</em> - diameter
The formula of an area of a circle:

<em>r</em> - radius
We have <em>d = 2r = 4m → r = 2m.</em>
<em>Substitute:</em>
<em>Use π ≈ 3.14</em>
