Question

if cosectheta theta =2 and cot theta =root 39 where theta is an acute angle, find the value of p

Answer 1

cosec @ = h/p = 2/1

By using Pythagoras theorem,
b = √(h^2 - p^2)
b = √(2)^2 - (1)^2
b = √(4-1)
b = √3

Now cot @ = b/p = √3/1

It is given cot @ = √3p
√3p = √3/1
p = 1

So your required answer is B) 1
