The current area is 15 x 9 = 135 square feet.
He wants to increase both the length and width by X:
Set up an equation:
(15 +x) * (9 +x) = 135 * 2
Simplify :
x^2 + 24x + 135 = 270
Subtract 270 from both sides:
x^2 + 24x - 135 = 0
Use the quadratic formula to solve for x:
-24 +/- √(24^2 - 4(1*-135) / 2*1
x = 4.7 or -28.7
The answer has to be a positive value, so x = 4.7 feet.
<h3>The measurement of the central angle is 135 degrees</h3>
<em><u>Solution:</u></em>
<em><u>The length of arc when angle given in degrees is given as:</u></em>

Where,
r is the radius
is the central angle in degrees
From given,

Substituting the values we get,

Thus the measurement of the central angle is 135 degrees
According to "Black Hole Beginnings," the destruction of some stars results in an an intense gravitational pull.
To answer the question, we need to know what Black Holes are.
<h3>What are Black Holes?</h3>
Blackholes are regions of space in which no matter can escape
<h3>Characteristics of black holes</h3>
- Black holes are formed from the remnants of large star that dies in a supernova
- As long as the star is three times or more larger than the sun, it will collapse
- The gravitational force on the star causes it to collapse into a black hole
So, when black holes are formed, some stars are destroyed and collapse due to intense gravitational forces.
So, according to "Black Hole Beginnings," the destruction of some stars results in an an intense gravitational pull.
