Question

Please help explain??

Answer 1

goto the required angle L corner,
and stare at the triangle

Answer 2

opposite side = ?
adjacent side = ?

Answer 3

7/6 right?

Answer 4

Yes !

Answer 5

tan L = 7/6

Answer 6

next what ? :)

Answer 7

you need angle L,
not the tangent of angle L

Answer 8

I'm going to find tan of each angle measures to see if it matches to 7/6 which would equal
.8571 is that right?

Answer 9

you can do that,
but there is a king's way of doing this

Answer 10

How is that? : )

Answer 11

\(\large \tan~ L = 7/6 \)


take tan inverse both sides

\(\large \tan^{-1} \tan~ L = \tan^{-1} 7/6 \)

Answer 12

left side,

\(\large \tan^{-1}~~~ and ~~~~ \tan~ \)

eat eachother out

Answer 13

\(\large \tan L = 7/6 \)

take tan inverse both sides

\(\large \tan^{-1} \tan L = \tan^{-1} 7/6 \)

\(\large L = \tan^{-1} 7/6 \)

Answer 14

use ur calculator and find the right side
