v+ (-456) =213

b = 190 in.

Step-by-step explanation:

In the given triangle b is the side adjacent to <A= 37°.Side AB = 238 in is the hypotenuse.

To find b we look for the trigonometry ratio which invlves adjacent and hypotenuse .

Cos A=

Using cos of the angle to find b we have:

Or b= 238 cos 37.

b =190.0752

Or b=190 (to nearest whole numner)
