In order to match each of the pairs you need to divide the numerator by the denominator to make it into a decimal.
Below are the pairs:
21/25 = 84%
13/20 = 65%
2/5 = 40%
3/4 = 75%
3/5 = 60%
29.9, 30.0,30.1,30.5,30.7,30.08,31.0,31.0
the number of data is 8 elements so the medium will be the 3rd and 4th number
so the medium is 30.5 and 30.7
We know that one regular hexagon is consist of the six equilateral triangles.
One of this is ΔAFM every angle in this triangle worth 60°, according to this
∡AFM=60°.
ΔABC is isosceles triangle with angle ∡ABC=120°, because every interior angle in regular hexagon worth 120°.
Angles ∡BAC=∡BCA=30°. Total sum of angles in one triangle is 180°.
∡ACF≅∡BCA=30° at the end we can conclud that angle ∡FAC=90° WHY?
Good luck!!!
