Question

Find sec A and cot B exactly if a = 8 and b = 7.

Answer 1

sec A= 1.01 and cot B =8.25

Explanation:

Given :

sec A and cotB if a =8 and b=7

Now,

=
`sec A=(1)/(cos A) \\\\(1)/(cos 8) \\\\(1)/(0.99) \\1.01`

and

`cot B=(cosB)/(sin B) \\cotB=(cos 7)/(sin7) \\cot B =(0.99)/(0.12) \\cot B =8.25`

Therefore, answer will be sec A= 1.01 and cot B =8.25
