If cot(theta)= 4/3, find csc(theta) (Picture provided)

kozerog [31]

Answer:

Step-by-step explanation:

If $\cot \theta=\dfrac{4}{3},$ then we can consider right triangle with adjacent leg 4 un. and opposite leg 3 un.. By the Pythagorean theorem,

$\text{hypotenuse}^2=\text{adjacent leg}^2+\text{opposite leg}^2,\\ \\\text{hypotenuse}^2=4^2+3^2,\\ \\\text{hypotenuse}^2=16+9,\\ \\\text{hypotenuse}^2=25,\\ \\\text{hypotenuse}=5\ un.$

So,

$\csc \theta=\dfrac{\text{hypotenuse}}{\text{opposite leg}}=\dfrac{5}{3}.$
