Question

If sin A =8/17 find the value of sec A cos A + cosec A cos A

Answer 1

Answer:

Step-by-step explanation:

sina = opp/hyp

so using the area of triangle,

17^2=8^2+adj^2

289=64+adj^2

289-64=adj^2

225=adj^2

√225=adj

adj=15

then cos a = 15/17

sec a = 17/15

cosec a =17/8

(17/15)15/17+(17/8)15/17

=1+15/8

=1+cot a
