Finding Missing Angles Facts, Examples & Summary

WebCross-multiplying is often used to solve proportions. As an example: 14/20 = x/100 Then multiply the numerator of the first fraction by the denominator of the second fraction: 1400 = Then, multiply the denominator of the first fraction by the numerator of the second, and you will get: 1400 = 20x. Solve by dividing both sides by 20. WebMar 3, 2024 · For example, if you know that 4 of the angles in a pentagon measure 80, 100, 120, and 140 degrees, add the numbers together to get a sum of 440. Then, subtract this sum from the total angle measure for a pentagon, which is 540 degrees: 540 – 440 = 100 degrees. So, the missing angle is 100 degrees. phil kouffman builder inc
