Explanation:
we know that
tanA = (perpendicular)/(base)
So taking right angle triangle
using pythagoras theorem
(hypotenuse)^2= (perpendicular)^2 + (base)^2
h^2 = 4^2 +3^2
h^2 = 16 +9
h ^2 = 25
h = 5
Now cosecA = hypotenuse/ perpendicular
cosecA = 5/4
cot A = base/ perpendicular
cot A = 3/5
sec A = hypotenuse/ base
sec A=5/3
