Find the attached image for the diagram of the question
A. 3 B √34 C √65 D √41
Answer:
The length of x, is √65
Step-by-step explanation:
To determine the length, x, we are going to apply Pythagoras theorem;
Consider triangle ABC;
BC² = AB² + AC²
5² = 3² + AC²
AC² = 5² - 3²
AC² = 25 - 9
AC² = 16
AC = √16
AC = 4
Now, we can calculate length, x
Consider triangle ACD
AD² = AC² + CD²
x² = 4² + 7²
x² = 16 + 49
x² = 65
x = √65
Answer:
Step-by-step explanation:
The formula of an area of a circle:
<em>r</em> - radius
We have the endpoints of a diameter of a circle.
The formula of a distance between two points:
Substitute the coordinates of the given points A(3, 4) and B(10, 4):
Therefore we have the length of the diameter: <em>d = 7</em>
We know: <em>d = 2r.</em> Therefore
Substitute to the formula of an area:
<em>There is no such answer in the answers to choose.</em>
<em>Apparently you have some error in the coordinates of the endpoints.</em>
