( ANSWER? )

AB = 4/cos25

Put in calculator and put to the nearest hundredth or 2 dp

Step-by-step explanation:

The angle 25 is the starting point and adjacent is 4 and the unknown or we will call it x is the hypotenuse.

We will use CAH

Cos25 = 4/x

We need x by itself so

x = 4/cos25

Put in calculator and put to the nearest hundredth or 2 dp

=

i believe the answer is c.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
