By definition, an isosceles triangle has 2 of the 3 sides with the same length. From this, we already know that the third side must be or 5 or 12.
We also know that, for every triangle, the sum of two sides must be always bigger than the third side, for any combination.
From this second affirmation, we know that the third side can not be 5, because:
From this, we conclude that the third side of an isosceles triangle with sides equal to 5 and 12 is equal to 12.
Answer:
Step-by-step explanation:
When you add fractions with different denominators, you need to find the Least common denominator (LCD):
Descompose the denominators (5 and 15) into its prime factors and then choose the commons and non-commons with the highest exponents:
Divide the LCD by each original denominator of each fraction and multiply the result by each original numerator of each fraction. After this, you can add the numerators and reduce the fraction.
Then:
