Because ΔCDF is similar to ΔBDE, the corresponding sides are proportional
CD:BD=FD:ED
(3.63+5.19):5.19=(x+4.45):4.45
5.19(x+4.45)=(3.63+5.19)*4.45
5.19x+5.19*4.45=3.63*4.45+5.19*4.45
5.19x=3.63*4.45=16.1535
x≈3.11
you can also do DB:BC=DE:EF. You'll get the same result.
Answer:
69
Step-by-step explanation:
A hexagon has 720 degrees in total. You add allthe numbers which is 513 degrees. Then you subtract them which is 207 degrees. Finally you divide 207 by 3 which is 69 :)

The answer is "Equiangular, Equilateral"
Step-by-step explanation:
please find the complete question in the file.
In this question, the answer is equiangular, in which the triangle was considered an equilateral triangle with 3 parallel inner angles. It's the measurement of each of these interior angles is 60 degrees, inside an equiangular triangle, and although there 3 parallel sides of an equiangular triangle, so it is just like an equilateral triangle.
