Answer:
see explanation
Explanation:
∠ FDJ and ∠ HDR are vertically opposite angles and are congruent, that is
∠ FDJ = ∠ HDR ( substitute values )
10x - 3 = 6x + 25 ( subtract 6x from both sides )
4x - 3 = 25 ( add 3 to both sides )
4x = 28 ( divide both sides by 4 )
x = 7
Then
∠ FDJ = 10x - 3 = 10(7) - 3 = 70 - 3 = 67°
∠ FDJ = ∠ HDR = 67°
