I really don’t know but my guess is 3
Answer:
x = 1/7
Step-by-step explanation:

x = 1/7
60 minutes is 20% of 300 minutes
Area of the parabolic region = Integral of [a^2 - x^2 ]dx | from - a to a =
(a^2)x - (x^3)/3 | from - a to a = (a^2)(a) - (a^3)/3 - (a^2)(-a) + (-a^3)/3 =
= 2a^3 - 2(a^3)/3 = [4/3](a^3)
Area of the triangle = [1/2]base*height = [1/2](2a)(a)^2 = <span>a^3
ratio area of the triangle / area of the parabolic region = a^3 / {[4/3](a^3)} =
Limit of </span><span><span>a^3 / {[4/3](a^3)} </span>as a -> 0 = 1 /(4/3) = 4/3
</span>
<h2>
The required "option B)
" is correct.</h2>
Step-by-step explanation:
You can refer figure:

To find, the value of x = ?
We know that,
Consecutive angles are supplementary
The diagonals bisect the angles.

Divided by 2 both sides, we get
⇒ 
⇒ 
⇒ 
⇒ 4x = 
⇒ 
⇒ 
∴ The value of x =
Thus, the required "option B)
" is correct.
