Find x and the measure of each side. Round to two decimal places, if necessary.
natta225 [31]

The values of the triangles are as follows:

  • x = 7 units
  • GH = 21 units
  • HI = 21 units
  • GI = 12 units

<h3>How to find angles and side of a triangle?</h3>

The triangle is an isosceles triangle because two sides and angles are equal. Therefore,

4x - 7 = 2x + 7

4x - 2x = 7 + 7

2x = 14

x = 14 / 2

x = 7 units

GH = 4(7) - 7 = 28 - 7 = 21

HI = 2(7) + 7 = 14 + 7 = 21

GI = 7 + 5 = 12
