Question

Answer this question please​

Answer 1

Answer:

Tan ∅ = 5/13 and it is given that ∅ lies in 3rd quadrant

Hence, sec ∅ and cosec ∅ will have negative values

now Tan ∅ = (opposite side) / (adjacent side)

hence we know the values of opposite side and adjacent side as 5 and 13.

We can find out hypotenuse by using Pythagoras theorem, and hypotenuse turns out to be  √194;

∴ Sec ∅ = (hypotenuse) / (adjacent side) = - 13/√194 ( negative cuz its in 3rd quadrant)

cosec ∅ = (hypotenuse) / (opposite side) = - 5/√194

Answer 2

Answer:

sec teta = 1.063

cosec teta = 2.74

Step-by-step explanation:

sec teta = 1 / cos teta

cosec teta = 1/ sin teta

so by using Pythagoras theorem I have found the hypoteneous value =

$\sqrt{opps {?}^{2} + adjacent {?}^{2} }$

hypoteneous value= 13.71

cos teta = 0.948

therefore sec teta = 1/cos teta = 1/0.948=1.063

also sin teta = 0.364

therefore cosec teta = 1/sin teta = 1/0.364=2.747
