V<span>ertical angles are equal.
We have 4x = 2x + 18.
Then, 2x = 18;
x = 18 </span>÷ 2;
x = 9 degrees;
The measure of angle DBE is 2 × 9 + 18 = 36 degrees.
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that
Triangle ABC and ADE are congruent triangles by SSS Theorem postulate
therefore

Answer:
Angles with the same measure are congruent, so Z1 = Z2.
Step-by-step explanation:
D. cause you gotta isolate your variables (the cereal boxes) then get rid of the coefficent (2)
