<h3>Given</h3>
  • PQ = QR . . . . . . Q is the midpoint of PR
  • PQ = 3x+14
  • QR = 7x-10
<h3>Find</h3>
  • x
<h3>Solution</h3>

Put the given expressions in the given relation.

... 3x +14 = 7x -10

Subtract the left side.

... 0 = (7x -10) -(3x +14)

... 0 = (7-3)x +(-10-14) . . . . . simplify

... 0 = 4x -24

Divide by the coefficient of x.

... 0 = x - 6

Add the opposite of the constant.

... 6 = x

The value of x is 6.

attashe74 [19]

If the angle G is moved to a different spot in the circle the angle FGH and angle FEH in the cyclic quadrilateral will change to make it supplementary.

<h3 /><h3>What is a cyclic quadrilateral?</h3>

A cyclic quadrilateral is quadrilateral inscribed in a circle. It has all its vertices on the circumference of the circle.

Opposite angles in a cyclic quadrilateral are supplementary angles. That means they add up to 180 degrees.

Therefore, if he adjust point G to a different spot on the circle, angle FGH and FEH will adjust to become supplementary.
