Answer 1

Answer:

The bisect will be after 3.5cm

Answer 2

1st question

Given,

• Draw a line segments AB=7 or cmAB=7 cm and bisect it.

Following steps:

• Draw a line segments AB=7 or cmAB=7 cm using scale.

• Take AA as center and 4 or cm4 cm (more then half of ABAB length) as radius draw arc on above and below of line ABAB

• Take BB and same radius draw two arc above and below of the line ABAB which cuts before arc at XX and YY

• Join XYXY

• Hence, XYXY be the bisect line of the line ABAB .

2nd question

The value of sec thetasecθ is equal to $\sqrt{2}$

$\orange{\bigstar}\:\:{\underline{\boxed{\bf\red{Brief\:Explanation}}}}$

We have, tan thetatanθ = 1

To find, the value of sec thetasecθ = ?

∴ $tan \:thetatanθ \:= \:1$

⇒ $tan \: thetatanθ \: = \: tan \: 45tan45$

We know that,

Using trigonometric,

$tan \:45tan45\: = \:1$

⇒ $thetaθ \:= \:45°$

∴  $sec\: thetasecθ$

= $sec \:45\:=\:sec45$

= $sqrt{2}$

The value of sec thetasecθ = $\sqrt{2}$

Thus, the value of sec thetasecθ is equal to $\sqrt{2}$
