Answer 1

x=26

Explanation:

fdg is a 90 degree angle. 3x+12 3x26=78 78 plus 12 equals 90

Answer 2

If EFGH is a rhombus, then the diagonals are perpendicular. Therefore m∠FDG = 90°.

Therefore we have the equation:

3x + 12 = 90 subtract 12 from both sides

3x = 78 divide both sides by 3

x = 26
