Press SIN 4 3 2ND [ANGLE] 1 3 0 2ND [ANGLE] 2 ENTER

2ND [ANGLE] 1 gives you the degrees symbol, 2ND [ANGLE] 2 gives you the minutes symbol. If you need seconds, use ALPHA ["] (on the + key).

Note that this usually won't give you an EXACT value, but only a ten-digit approximation.

At first, you have to use DEGREE mode and after that you can convert your angles into DMS mode. See captured image below

First, check if the calculator is in degrees. Do this by pressing mode and selecting degrees (it should be about the third option down)

The TI-84 doesn't have a dedicated button for secant so you will just have to enter it as 1/cos(-1.2) or cos(-1.2)^-1

You can add angle measures by hitting 2nd angle and choosing the degree option. Put this after a value (e.g. 90(degrees symbol)) and add you can add angles that way. Be sure that you are in degree mode when doing this (you can use the radian symbol for adding radians too). Still, this is a very tedious process and I recommend just adding angles as regular values (e.g. 90 + 200 = 290) and correcting for degrees manually.

The DMS symbols are available under the ANGLE menu

Press [2nd][APPS] (ANGLE)

Under that menu you find the degree and minute symbol. To enter the seconds unit you use the key sequence [ALPHA][+] (")

To enter 1deg 15 minutes and 37 seconds

1 [2nd][APPS] [1:deg] 15[2nd][Apps][2:'] 37 [ALPHA] [+]

To enter a number in decimal degrees (eg 15.37)

Press [2nd][APPS] (ANGLE)

Under that menu you find the degree and minute symbol. To enter the seconds unit you use the key sequence [ALPHA][+] (")

To enter 1deg 15 minutes and 37 seconds

1 [2nd][APPS] [1:deg] 15[2nd][Apps][2:'] 37 [ALPHA] [+]

To enter a number in decimal degrees (eg 15.37)

- If angle unit is the degree just enter 15.37
- If angle unit is the radian , you must specify the angle unit as degrees: To enter 15.37 degrees you type 15.37 [2nd][Apps][1: degree] [ENTER].

- Enter the seconds number, ex 32
- Press [ALPHA][+] (") to access the double quotation mark.
- Screen echoes 15 deg 25' 32"
- Press [ENTER]
- Calculator converts this in decimal degrees 15.42555556

Your calculator is set in radians. Press mode key. Arrow down to 3rd line. Highlight degree and press enter. Your calculator is now in degrees, not radians. To get out of the mode screen and back to home screen, press 2nd and then mode.
