In my science math PBL class we are doing a project. The project consist of triangle, finding the missing angles of a triangles, and energy.Me and my gruop mebers got to make a ramp out of science and math book and a 6 foot wooden board. We are making a ramp because me and my group are going to roll an object down it to see how fast it will go down the ramp. All 3 of us have different ramps so it will be all different times. For my ramp I’ve got 1 math book and 3 science books. The angle that the stack of books created is a 450 angle. The way I solved for the missing angle by doing inverse property of adding.The equation was 90+45+x=180 and the way that I solved it is by doing 90+45 first which I got 135. Then I Subtracted 135 by 135 and …show more content…

So to find the missing angle of a right triangle you will have to add up the two angle that you already know and then subtract that number by 180 to find the missing angle of that triangle. The reason that we us 180 is because for angle triangle that you will have will always add up to 180 because 180 equals a straight line.
Another thing that I know is that there are 3 different types of energy that will be used in are protected. There is Kinetic energy, Potential energy, and Gravitational Potential energy. Kinetic energy is energy due to motion it is based off of speed and mass. For example, a ball going down a hill is Kinetic energy because it is moving. Potential energy is stored energy due to the interaction between objects or particles. For example, if a ball is on a top of a hill and still. Gravitational Potential energy is stored energy between earth and an object which depend on the object weight, and height. For example, I have a book and it is 3 feet off the ground, that is Gravitational …show more content…

Then we used a 6 foot board so the glue stick will roll down. We also used pencil to write down the times and parer so we could have something to write on.
The first thing that was done is my process was to find what the triangle was going to be. Then we used the stacked up the book and then put the the wooden board on the stack out books and had to make sure that the blue tape was right on the edge of the books. After that i had to roll the glue stick down the 6 foot wooden board and had to make sure my time keeper had the time that i started to the time I finished on the spot unless the roll would not be active. Last I the writer wrote down the time and that process went for ten time until we were done with mine but then we had to test Ryan's and Julian.
For the data i had only 2 numbers (6667 and 5455) that i had to find for the mean, median, mode and range, Julian had 3 numbers (5000, 6667, and 7500) to find and Ryan had 3 numbers (10000, 8571, and 18571) also. My mean was 5818.6, Julian’s was 6750.2, and Ryan’s was 9485.5. My mode is 5455, Julian’s is 6667, and Ryan’s is 8571. My median is 5454, Julian’s is 6667, and Ryan’s is 9285.5. Last but not least the range of my data is 1212, Julian’s is 2500, and Ryan’s is
