Question

Is this right? in the triangle below what ration is csc 0?

Answer 1

`(13)/(5)`

Explanation:

we know that

`csc(\theta)=(1)/(sin(\theta))`

In this problem

`sin(\theta)=(1.5)/(3.9)`

substitute

`csc(\theta)=(3.9)/(1.5)`

Multiply by 10 both numerator and denominator

`csc(\theta)=(39)/(15)`

Divide by 3 both numerator and denominator

`csc(\theta)=(13)/(5)`
