Answer:
21.7 metres (assuming the triangle is a right triangle)
Step-by-step explanation:
Assuming this is a right triangle, we can simply use the Pythagorean Theorem, which states that in a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 20, b = 8.5, and R = c. Plug these in:
a² + b² = c²
20² + 8.5² = R²
400 + 72.25 = R²
472.25 = R²
R = √472.25 ≈ 21.7 m
Thus, R is about 21.7 metres.
