Answer:
A
Step-by-step explanation:
In a parallelogram the opposite angles are congruent, thus
∠ JHF = ∠ JEF = 142°
∠ JHF and ∠ FHG are adjacent angles and are supplementary, thus
∠ FHG = 180° - 142° = 38°
The sum of the 3 angles in a triangle = 180° , thus
∠ HFG = 180° - (90 + 38)° = 180° - 128° = 52° → A

Let's solve your equation step-by-step.<span><span><span>−18</span>−<span>6k</span></span>=<span>6<span>(<span>1+<span>3k</span></span>)
</span></span></span>Step 1: Simplify both sides of the equation.
<span><span><span>−18</span>−<span>6k</span></span>=<span>6<span>(<span>1+<span>3k</span></span>)
</span></span></span><span>Simplify: (Show steps)</span><span><span><span>−<span>6k</span></span>−18</span>=<span><span>18k</span>+6
</span></span>Step 2: Subtract 18k from both sides.<span><span><span><span>−<span>6k</span></span>−18</span>−<span>18k</span></span>=<span><span><span>18k</span>+6</span>−<span>18k</span></span></span><span><span><span>−<span>24k</span></span>−18</span>=6
