Answer:
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:
It can be concluded that the intersection of a chord and the radius that bisects it is at right angle. The two are perpendicular.
Step-by-step explanation:
i. Construct the required circle of any radius as given in the question, then locate the chord. A chord joins two points on the circumference of a circle, but not passing through its center.
ii. Construct the radius to bisect the chord, dividing it into two equal parts.
Then it would be observed that the intersection of a chord and the radius that bisects it is at right angle. Thus, the chord and radius are are perpendicular to each other.
The construction to the question is herewith attached to this answer for more clarifications.
