Answer:
If we look at ΔBDH, we notice that m∠BHG has to be 108 - 36 - 39 = 105°. Because x and ∠BHG are a linear pair we know that x = 180 - ∠BHG = 180 - 105 = 75°.
solution,
<B+<D+<GHI=180°
or, 36+39+<GHI =180°
or,75°+<GHI=180°
or, <GHI=180°-75°
<GHI=105°
Again,
X=180°-<GHI
=180°-105°
=75°
Hope this helps...
Good luck on your assignment..
