Ответ:
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=![\frac{Adjacent}{Hypotenuse}](/tpl/images/0339/6456/55007.png)
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)
