Answer:
x=4
Step-by-step explanation:
√x+12=x
x+12=x2(Square both sides)
x+12=x2
x+12−x2=x2−x2(Subtract x^2 from both sides)
−x2+x+12=0
(−x−3)(x−4)=0(Factor left side of equation)
−x−3=0 or x−4=0(Set factors equal to 0)
x=−3 or x=4
x=−3(Doesn't work in original equation)
x=√x+12
Answer:
Step-by-step explanation:
we know that
Using proportion
Answer:
Option 4 is the right answer.
Step-by-step explanation:
As we know in the given circle area of minor segment having an angle ∅ and radius of the circle r is shown by
Area of the minor segment / Area of the circle = ∅ / 360° (∅ is in degrees)
Area of the minor segment / πr² = ∅ / 360°
Area of the minor segment = (∅ / 360°) × πr²
Therefore Option 4 is the right answer.
