Right angle trigonometry?

Question

Ok, i have a maths assignment and one of the questions says using your knowledge of right angle trigonemtry find this thing.

now it doesnt matter what the "thing" is but what i am asking is if the the "sine" rule is considered right angle trigonometry? because that seems to be the only way to answer this question.

Answer 1

Yes, you can use the sine rule.  I just did trig and thats what we did.  But I found a site for you:

if you ever cant do a question, type it in google or something and it should help you

Answer 2

Yes, for right triangle trigonometry you use the definitions of sine, cosine or tangent or the Pythagorean Theorem.

Problems would look like

sin 40º = a / 52     or sin @º = 3/5

Answer 3

dude Sine rule and cosine rule are refered to NON-RIGHT ANGLED TRIANGLES

Answer 4

yea dude sine rule is applicable for ryt angled triangles...for eg... an isoscles triangle if the syds r a,a and root a(hypotunese) ...if u apply the sine rule it still works...

Answer 5

sinus rule in threeangle is :

a/sin(A) = b/sin(B) = c/sin(C)
