Question

The coordinates of the vertices of an isosceles triangle are shown. The x-coOrdinate of one oft the vertices is missing. Which expression represents the missing X-coordinate? (?, c) (a, 0) (b, 0). what is ?
​

Answer 1

Answer:

( 1.6)

Step-by-step explanation:

(x−1)2+(y−3)2=(x−(−2))2+(y−7)2

(x−1)2+(y−3)2=(x+2)2+(y−7)2

=2x+1−6y+9=4x+4−14y+49

⇒6x−8y+43=0

By substituting (65,6)

⇒6×65−8×6+43

⇒0

Hence (65,6) is answer.
