OMG!!!
What an empty blog...
No one was blogging so Dr. Eviatar asked me to do a post. I wasn't paying much attention last class because I'm feeling lazy. Anyways, she helped us with some of the questions on Exercise 17: Trigonometry. I didn't remember how she do it, so i tried it on my own, please take a look and just blame me for any errors.


4.

BD-BC=CD

BD

Tan 38= 40/A

A= 40/Tan 38
Adjacent= 51.2= BD

BC

Tan 52= 40/A
A= 40/Tan 52
Adjacent= 31.4= BC

BD- BC= CD 51.2-31.4=CD 19.8= CD


5.

<EDC=?


BE

Tan 20= O/8
Tan 20 (8)= O
2.91= Opposite

BC- BE= EC
6- 2.91= 3.09


Tan <EDC= O/A
Tan <EDC= 3.09/8
Tan <EDC= 0.386= 21.1 degrees







Finish finally.
I'm not sure who haven't blog yet so I'll let Dr. Eviatar to pick the next blog.
T.Y. for viewing I guess.
