18 Superfícies
Step-by-step explanation:
We know that the sum of the interior angles must be 180, so we have
So, the three angles are
And we can already conclude that the triangle is isosceles.
The two equations are 3.79x or x*3.79.
They aer both equivalent because if you plug in a random answer, you will get the same answer.
