Answer:
It's an angle bisector and it was found using a compass
Step-by-step explanation:
First you use the compass to make a marking in the angle
Then you move the compass to the D and make another marking after that you move the compass to E (Make sure to use the same compass setting) and make a marking that intersects with the marking of D which creates F. Last you use a straight edge to make the angle bisector of ABC. (Sorry if you don't understand this it was difficult for me to explain)
5(5+x) = 6(6+4)
25+5x = 60
5x = 35
x = 7
-----------------
3(3+5) = 4(4+x)
24 = 16 + 4x
4x = 24-16
4x = 8
x = 2
Answer:
0.005371
Step-by-step explanation:
Given that a fair coin is tossed 11 times.
Since coin is fair probability for head p = 0.5 and q = prob for tail =0.5
Each trial is independent of the other. Hence X no of heads is binomial with 
Prob for getting 10 heads out of 11 tosses
=P(X=10)
=
The answers are published data, survey, and observational study in that order on elearning for anyone still wondering.
