Question 867439
Using the info given, solve for the missing value of the right triangle. Round each angle to the nearest degree, each length to the nearest tenth, & each trigonometric value to four decimal places, if necessary.
Hypotenuse = 255 ft
θ = 25°
Adjacent side = ? 
***
cos 25˚=adjacent side/hypotenuse
adjacent side=cos 25˚*255=231.1 ft
On a scientific calculator set to degree mode, enter cos 25˚, press the times key (x), enter 255, then press the enter key(=) to display the answer.
