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.

answer: close to 0 close to 1 of 10 close over 100 reward: five points and cashapp:5$
A probability close to 1 indicates a chance event is very likely to occur. The probability of such an occurrence is a number. The correct option is option A.
The probability of such an occurrence is a number used in science to describe how likely it is that the event will take place. In terms of percentage notation, it really is represented by a value between 0 and 1, or between 0% and 100%.
The odds of two complementing events A and B happening, either A happens or B happens, sum up to 1. outcomes are complimentary, the likelihood of "heads" is equal to the likelihood of "tails," and the likelihood of any one of the two possible outcomes is equal to half. A probability close to 1 indicates a chance event is very likely to occur.
Therefore, a probability close to 1 indicates a chance event is very likely to occur. The correct option is option A.

The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable and if the highest power in the quation is 2 then it is a quadratic equation.
----> Quadratic Equation
y +3 = -2x² +5----> Quadratic Equation
----> Quadratic Equation
----> Non Quadratic Equation
----> Non Quadratic Equation
y = 5 x(x + 9) - 8----> Quadratic Equation
----> Quadratic Equation
Answer:
2. y + 3 = -2x^2 + 5
3. y = 2x^2 - 8x + 6
6. y = 5x (x+9) - 8
