Answer: x = 4</h3>
==================================================
Explanation:
Use the remote interior angle theorem. This says a pair of interior angles always add to the measure of the exterior angle that is not adjacent to any of the interior angles, so basically what your diagram is showing.
(interior angle C) + (interior angle D) = exterior angle
(46) + (-1+8x) = 18x+5
8x+45 = 18x+5
8x-18x = 5-45
-10x = -40
x = -40/(-10)
x = 4
85986 7/43 using kcf it becomes 14788588/86 times 1/2(flipped)
Answer:
C. Addition Property of Equality
Step-by-step explanation:
Addition Property of Equality allows one to add the same quantity to both sides of an equation.
