Question

If cotA= 8, then secA= ....​

Answer 1

Answer:

We know that,

cot theta=adjacent side/ opposite side

If adjacent side=8

opposite side=1

then, by Pythagoras theorem

AB²+BC²=AC²

1²+8²=AC²

1+64=AC²

65=AC²

AC=√65

AC=8.06

we know that,sec theta=hypotenuse/ adjacent side

8.06/8

Therefore ,sec A =8.06/8
