Question

17. If 15 cot A = 8, then cosec A=
(A)17/8
(B) 17/15
(C) 8/15
(D) 15/8​
explain

Answer 1

Answer:

(B) 17/15

Step-by-step explanation:

cot A=8/15=base/perpendicular

now 8²+15²=hypotenuse²

64+225=h²

289=h²

h=✓289

h=17

cosec A=h/p=17/15

Answer 2

Answer:

cot=8/15=b/p

let's the triangle of side=k

h2=p2+b2

h2=(15)square+8square

h2=225+64

h=root289

h=17

cosec=h/p =17/15

so, option (c) 17/15 is right
