Alright... Time To Blog...

During class, Dr. Eviatar did some things about right triangles. So I think that's what i'm putting here. Just notify me if there's something wrong. So good luck guys and take a look at it!! :P

So Let's see.... Here's the one she did.

SIN A/a = SIN B/b = SIN C/c

Angle B = 72°

Angle C = 67°

b = 42

c = ?

b/SIN B = c/SIN C

42/SIN 72̲̲̲̲̱̱̱̱̲̲̲̲̱̱̱̱° = C/SIN 67°

(42) (SIN67°/SIN72°)

So it will be...

(42)(SIN67°) = 36.5

After that... Do this like :

36.5/SIN72°

c = 40.3

There you have it.

Oh,, Finally... I almost forgot, there's a homework that Mrs. Eviatar wants us to finish.

Homework (Exercise 19 # 2-6, 17)

2.

Find The Value of X.

3.

Find b.

4.

Find a.

5.

Find Angle A.

6.

Find Angle B .

17. The school flagpole is 14m high. A student measures the angle of elevation of the top of the pole to be 31°. She then moves closer to the pole and finds the angle of elevation has increased to 48°. Find the distance that she moved from the first measurement to the second.

Alright!! Finally I'm done.... Take a look at those and check if there's something wrong... Good luck to all of you guys!!.. :)

SO I THINK THE NEXT BLOGGER WILL BE AKEEM NOW!!!

YOUR THE ONE WHO'S NEXT HAHAHAHAH!! :P

HOPE YOU DO IT!!
