Given sin x=13/85 and tan x=13/84 .

olga55 [171]

ANSWER:

We know that,

tanΘ = sinΘ/cosΘ

cosΘ = sinΘ/tanΘ

So, cosΘ = 13/85 ÷ 13/84

13/85 × 84/13
84/85.

White raven [17]

Answer :

1 (i).
$slope \: = - \frac{1}{6}$
(ii).
$midpoints \: = (1 \: \: \frac{17}{2} )$
(iii) .
$distance \: = \sqrt{37}$
2(i).
$slope \: = 2$
