Question

if cot A=12/5 find the value of (SinA+cosA) cosecA

Answer 1

Answer:

answer is.......

17/5

Answer 2

Step-by-step explanation:

(sinA+cosA)cosecA

we know that

$coseca = \frac{1}{sina}$

so by putting cosecA=1/sinA

so

(sinA+cosA)/sinA

$\frac{sina}{sina} + \frac{cosa}{sina}$

1+cosA/sinA

and cosA/sinA is equal to cotA

so,

1+cotA

as cotA=12/5 (given)

so

1+cotA=>1+12/5

=>(5+12)/5

=>17/5
