Question

in a∆ABC right angled at B, if AB=4&BC=3, find all the six trignometic ratios of ∆A

Answer 1

First let find Hypotenus

H=√p²+b²

Here p is perpendicular and b is base

H=√ 3²+ 4²= 5

Now
SinA = p/h = 3/5
CosA= b/h = 4/5
TanA =p/b = 3/4

And reverse the ratio for getting Cosec sec and cot

Hope this helps u
