You can put this solution on YOUR website!
you will want to use your scientific calculator for this.

if you don't have a scientific calculator, try this online one.

some things you need to know.

most scientific calculators only have a sine, cosine, or tangent function.

secant is equal to 1 / cosine.

cosecant is equal to 1 / sine.

cotangent is equal to 1 / tangent.

also:

minutes are equal to degrees divided by 60.

seconds are equal to degrees divided by 3600.

54 degrees and 23 minutes is equal to (54 + 23/60)

35 degrees and 21 minutes and 45 seconds is equal to (35 + 21/60 + 45/3600).

minutes are indicated by the ' symbol.

seconds are indicated by the " symbol.

be sure to see the calculator to degrees.

you can also do the conversion to degees ahead of time.

55 degrees and 21 minutes is equal to 55 + 21/60 which is equal to 54.83333333 degrees.

36 degrees and 10 minutes is equal to 36 + 10/60 = 36.1666666667 degrees.

35 degrees plus 21 minutes plus 45 seconds is equal to 35 + 21/60 + 45/3600 which is equal to 35.3625 degrees.

stick those in your calculator and you'll get the same answer as before.
