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°
So the answer will be...
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!!
