The sum of the 3 angles needs to be 180.
To find the third angle subtract to the known angles from 180.
180 - 48 - 71 = 61
The third angle is 61 degrees.
Natural numbers are always rational numbers since they can be expressed as fractions with a denominator of 1.
Natural numbers are always rational numbers. A rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. Since natural numbers are a subset of integers (positive whole numbers), they can be expressed as fractions with a denominator of 1. For example, the natural number 5 can be written as the fraction 5/1, which is a rational number.
