Answer:
The answer to your question is given below
Step-by-step explanation:
Let 'a' and 'b' be the length of the first two sides of the triangle and let 'c' be the longest length of the triangle.
The following data were obtained from the question:
Length of a = 17 m
Length of b = 144 m
Length of c = 145
For the triangle to be a right-angled triangle, then it must certify the pythagoras theory which states that the square of the two sides in a right-angled triangle is equal to the square of the longest side.
Thus, we can prove that the triangle is a right-angled triangle as illustrated below:
a² + b² = c²
Length of a = 17 m
Length of b = 144 m
Length of c = 145
17² + 144² = 145²
289 + 20736 = 21025
21025 = 21025
From the above illustration, we can see clearly that the square of two sides of the triangle is equal to the square of the longest side. Therefore, the triangle is a right-angled triangle.
