The value of x from the given circle is 12

<h3>Circle theorem</h3>

Angle at the vertex of the circle is half the angle at its intercepted arc.

From the given circle;

The measure of <DEF = 80/2 = 4x -8

Equate both angles

4x - 8 = 80/2

Add 8 to both sides

4x - 8 + 8 = 40 + 8

4x = 48

x =12

Hence the value of x from the given circle is 12

Find the midpoint of a line segment that has the endpoints (3,5) and (5,-3) *

igor_vitrenko [27]

Answer:

<h3>The answer is (4 , 1)</h3>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3,5) and (5,-3)

We have

$M = ( \frac{3 + 5}{2} , \frac{5 - 3}{2} ) \\ = ( \frac{8}{2} , \frac{2}{2} )$

We have the final answer as

Hope this helps you
