Hello :
(-6a)-(-3a) =(-3a)-(0) = (0)-(3a) = (3a)-(6a) = -3a (arthmetic<span> sequence, the common - diff is : d= -3a the first term is : U1 = 6a
</span><span>a general rule for the n th term is : Un =U1+(n-1)d
Un = 6a +(n-1)(-3a) =
Un = 6a -3an+3a
</span>Un = -3an +9a

Answer:
<h2>m∠GEF = 18º since it is marked as congruent to ∠DEG, so putting them together we get m∠DEF = 36º. Since the angles in the triangle need to add to 180º and angles D and F are congruent, we could write the equation 2x + 36 = 180 where x stands for ∠F.</h2>
