Answer 1

Given:

The figure.

To find:

The value of a.

Solution:

We know that, in a right angled triangle

`\tan \theta =(Perpendicular)/(Base)`

In the given triangle,

`\tan (38^\circ) =(6)/(a)`

Multiply both sides by a.

`\tan (38^\circ)* a=6`

Divide both sides by
`\tan (38^\circ)`

`a =(6)/(\tan (38^\circ))`

The value of a is
`(6)/(\tan (38^\circ))`.

Therefore, the correct option is b.
