Answer:
Given: Point C is the center of circle.
To Find: ∠ A CB
Solution: Measure of arc A DB=312°
Angle made by complete circle=360°
⇒∠A DB + ∠ AC B= 360°[Total measure of complete circle]
⇒ 312° + ∠ AC B= 360°
⇒∠ AC B = 360° - 312°
⇒ ∠ AC B=48°

What is a Quadratic Equation?
- Quadratic equations are the polynomial equations of degree 2 in one variable of the type
where a, b, c, ∈ R and a ≠ 0.
- The standard form of a quadratic equation is
.
Here, the given equation is (2x+7)(x-5) = - 43 + jx
On simplifying the equation we get,
By comparing the given equation with the standard form of the quadratic equation we get,
a = 2
b = - (3 + j)
c = 8
Therefore,
Take the square root of both sides,
3 + j = ±8
Therefore,
3 + j = 8
j = 8 - 3
j = 5
or
3 + j = -8
j = -8 - 3
j = -11
Hence, the possible values of 'j' are -11,5.
