Step-by-step explanation:
-10x + 4 = -7x - 14 - 7x - 14
-10x + 4 = -14x - 28
4x = -32
x = -8.
Consider only triangle BDH. Interior angles B and D are given, and "x" is the exterior angle at H. The measure of that exterior angle is the sum of the measures of the opposite interior angles (B, D).
x = ∠B +∠D
x = 46° +33° = 79°
