Answer 7

@ikram002p do you know if 5/13is correct?

Answer 8

im not sure actually

Answer 9

Ok, well the formula for sec is \[\Large \frac{1}{\cos \theta}\]

Answer 10

right ok...

Answer 11

And that basically means to just reverse what cos is \[\Large \frac{1}{\cos \theta}=\frac{1}{\frac{adj}{hyp}}=1 \times \frac{hyp}{adj}= \frac{hyp}{adj}\]

Answer 12

ok

Answer 13

And what are the hypotenuse and the adj side to the angle?

Answer 14

Just plug those values in

Answer 15
