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 = ?
Of course I'm looking for the answer but I'm trying to get a better understanding of HOW to get the answer on a Science Calculator.

You can put this solution on YOUR website! 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.
