Which two options can you choose to copy files in your computer?

Go to the files or folders you want to copy. If you need help locating the files, use the Windows find feature.

Highlight the file or files you want to copy by clicking them once with the mouse. If you need to highlight more than one file, you can hold down the Ctrl or Shift keys on your keyboard or drag a box around the files you want to copy.

Once highlighted, right-click one of the highlighted files and select copy. Users may also press the Ctrl+C shortcut key, or in Windows Explorer, click Edit at the top of the window and choose Copy.

Open the destination folder, right-click an empty space in the folder, and choose paste. Or, open the File menu, choose Edit, then choose Paste.

Explanation:

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
