Answer 2

Answer:

Sin A = 15/17

Sec A = 17/15

Step-by-step explanation:

15 COT A = 8

so, Cot A = 8/15

We know that

CotA = CosA / Sin A

OR Cot A = Adjacent side / Opposite side

so, Adjacent side = 8

opposite side = 15

as it is right angled triangle.

By using pythagoras theorem,

Hypotenuse = 17cm

Now we can get the values

Sin A = Opposite side/Hypotenurse

Sin A = 15/17

Also we know

sec A = 1/ sin A = Hyp/opp.

Sec A = 17/ 15
