Let’s begin 40˚ You have a problem. How do you find the Hypotenuse? Its easy if you use trig functions. See my angle? Hahahajk ? 15
We all know our trig functions, right? Not really, so its important to learn them. Lets start with…. SOME OLD HOOKER COUGHED ACID HATEFULLY TOWARDS OBAMA ACCURATELY Sin Cos Tan Or it could be Some Old Hippie Caught A High Tripping On Acid. Remember this and you now know what trig functions mean.
For example If you have the measure for one angle (54˚) and the hypotenuse is 15 then you can find the other sides and angles. Use the COStrig function to solve for the Adjacent side of 54 degrees. Cos54= You then multiply 15 to get x by itself So you plug (15)cos54 and get your answer 54˚ 15 x
For another Example • You can use the SIN trig Function with this one So you would set it up like Sin30= You then need to get x by itself So you “swap” out the x and it ends up like this X= and just plug it into the calculator 30˚ x 20
Now for the Pentagon You are given the Apothem(a) and The Radius(r). To find the Measurement of one the Sides, use the pythagorean Theorum. Then multiply by two. r a
