Question

if cosec theta = 5/3 then gind the value of cos theta + tan theta



​

Answer 1

Answer:

31/20

Step-by-step explanation:

cosec ∅ = H/P = 5/3

Therefore H=5, P=3

By Using Pythagoras Theorem,

H²=B²+P²

B²=P²-H²

   =3²-5²

   =9-25

   =16

B=√16

B=4

cos ∅ = B/H = 4/5

tan ∅ = P/B= 3/4

Therefore,

cos ∅ + tan ∅  = 4/5 + 3/4

= 31/20
