WebNov 21, 2024 · Explanation: Since the sum of all angles in a triangle is equal to 180. Then in the left triangle, x + 54+ 40 = 180. x + 94 = 180. x = 180 − 94 = 86degrees. Also, x + z = … WebFortunately, there are mathematical summaries of your data that can convey a lot of information with just a few numbers. These summaries are called descriptive statistics.
