We know that
[area of a regular hexagon]=6*[area of one <span>equilateral triangle]
</span>210.44=6*[area of one equilateral triangle]
[area of one equilateral triangle]=210.44/6-----> 35.07 cm²
[area of one equilateral triangle]=b*h/2
h=7.794 cm
b=2*area/h------> b=2*35.07/7.794------>b= 9 cm
the length side of a regular hexagon is 9 cm
<span>applying the Pythagorean theorem
</span>r²=h²+(b/2)²------>r²=7.794²+(4.5)²------> r²=81--------> r=9 cm
<span>this last step was not necessary because the radius is equal to the hexagon side------> (remember the equilateral triangles)
</span>
the answer is
the radius is 9 cm
√8 = √(4x2) = 2√2
4√2 =4√2
2√2-4√2 = -2√2
8.1 I think but there's an app called, tiger something and it tells,you the answers
Answer:
A
Step-by-step explanation:
From the diagram, angle A is congruent to angle E. This is because they are both marked with the same symbol, signifying that they are congruent.
