In an isosceles triangle, one of the corners is obtuse, one of the sides is 20 m long, and the other 15 cm. Determine the length of the base of this triangle.
Since the triangle is isosceles, its two sides are equal.
Therefore, its base is a side equal to either 15cm or 20m
There is always a large side against an obtuse angle.
Hence, the required base = 20m
Answer: 20m
