Question

How do I find the value of the trig function? Number 1

Answer 1

From the trigonometric identities, we know that

`\sec \theta=(1)/(\cos \theta)`

From the given triangle, we can see that

`\cos \theta=(15)/(17)`

then,

`\sec \theta=(1)/((15)/(17))`

so, the answer is

`\sec \theta=(17)/(15)`
