If cot theta = 3/2, what is the value of csc theta?
Arturiano [62]

The value of csc theta is \frac{3. 61}{2}

<h3>How to determine the value</h3>

It is important to note that the ratio for cot is given as;

Cot theta = adjacent/opposite

cosec theta = hypotenuse/opposite

If cot theta = 3/2, then

Adjacent = 3

Opposite = 2

Using Pythagoras theorem, we have

Hypotenuse square = opposite + adjacent square

H = \sqrt{2^2 + 3^2}

H = \sqrt{4 + 9}

H = 3. 61

Cosec theta = \frac{3. 61}{2}

Thus, the value of csc theta is \frac{3. 61}{2}
