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.

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.
