THE answer is 7 1/6 Please go to cymath and you’ll see how to work it out
Triangle BCD is Isosceles triangle.
Angles C and B are the same and equal 36 degrees. Angle D= 180-(36•2)=180-72=108
Good luck.
Answer:
24x-1
Step-by-step explanation:
4x*2+16x-1
=8x+16x-1
=24x-1
That's its simplest form, I'm not sure I understand what you mean by describe.

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
