The length of Line BC is 10
A figure bounded by 3 sides and all the internal angles add up to 180 ° is called a triangle.
Triangles having the same corresponding angles measures and proportional side lengths are called similar triangles.
Considering Δ AXY and ΔABC
∠AXY = ∠ACB (corresponding angles are equal)
∠AYX = ∠ABC (corresponding angles are equal)
∠A is common in both the triangles
∴ We can say the triangles are similar .
Now, let H be the height of ΔABC and h be the height of ΔAYX
So, we can say,
So,
⇒
Now, substituting XY = 5 and in the above equation, we get
⇒ BC² = 100
⇒ BC = ± 10
Since BC is the length , so it cannot be negative.
So, the negative value is rejected.
∴ BC = 10
Option B is correct.
