The length of line BC will be 15 units. Option C is correct.
What is the definition of a right-angle triangle?
It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometric function.
According to Pythagoras, the sum of the squares of two sides equals the square of the longest side.
Apply Pythagoras theorem in right angle triangle ABC ;
AB²=AC²+BC²
Substitute the values from the digrame;
17² =8² +BC²
289 = 64 +BC²
289 -64 = BC²
BC²=225
BC=√225
15 = BC
The length of line BC will be 15 units.
Hence option C is correct.
