The value of x is:

Step-by-step explanation:
we have to use the quadratic formula to solve for x.
The equation is given as:

which could also be written as:

The quadratic formula for the quadratic equation of the type:
is given as:

Here we have:
a=4, b=-5 and c=8.
Hence, by the quadratic formula we have:

Hence, the value of x is:

Answer: 180
Angles in a linear pair are always supplementary. This means they form a straight angle or a straight line.
13 cm (approximately)
Step-by-step explanation:
Let the radius of the circle be 'r'.
Area of the circle = πr²
=> 132.7 = (22/7) r²
=> 6.5 ≈ r
Therefore, diameter = 2radius = 2(6.5) = 13 cm
