You can find the missing angle in a right triangle by subtracting 90 from the reference angle.
Scientific notation is used to shorten large numbers. The format for scientific notation is . The is a number under 10 such as 1.029 or 8.293. The is the number of decimal places to the right if its a positive exponent or the number of decimal places to the left if its a negative exponent. Below is an example of how to use scientific notation.
I recently learned how to find the GCF (Greatest Common Factor) of two numbers. The GCF is the highest integer that divides into the two numbers. In order to find it, you need to first find the prime factors of the two numbers, then compare the two groups of prime numbers and look for pairs as illustrated below. Take one number from each pair and multiply it with the other numbers you take from the pairs, the product is the GCF.

The purpose of this experiment was to discover the optimal placement of paperclips on a paper plane for it to travel farthest. The paper plane was tested with two paperclips in the front, two in the back, and without. Through experimentation, I found that the plane without weight travelled 3.9m, with two paperclips at the tip of the plane it travelled 3.7m and finally with the two paperclips at the back it travelled the furthest with a distance of 4.1m. I learned that some paper planes can benefit from the additional weight on the rear of the plane but in the future, I would want to test more designs to see how the weight distribution affects them in addition to finding a more reliable and consistent method of throwing the planes.
