Respuesta :

ABC is an isosceles triangle.
Sides : AB = BC
3 x - 7 = 2x
3 x - 2 x - 7 = 2 x - 2 x
x - 7 = 0
x - 7 + 7 = 0 + 7
x = 7
Segment AC:
AC = 3 * 7 - 7 = 21 - 7 = 14
Answer: C ) 14

The measure of AC from the figure is 14 units

Isosceles triangle

The given diagram is an isosceles triangle since the base angles are equal. From the given figure;

2x =3x - 7

Collect like terms

2x - 3x = -7

-x =-7

Multiply both sides by -1

x = 7

AC = 3X - 7

AC = 3(7) - 7
AC =14 units

Hence the measure of AC from the figure is 14 units
