Since the congruent operator is ≅ and since AD is congruent to BD, I'm going to assume that you want to prove that AD is congruent to BD.
1. DE is equal to CD by definition since D is the midpoint of CE.
2. AE is equal to BC since opposite sides of a rectangle are equal to each other.
3. Angle AEC is equal to Angle BCE since all angles in a rectangle are right angles and all right angles are equal to each other.
4. Triangles ADE and BDC are congruent to each other because we have SAS congruence for both triangles.
5. AD is congruent to BC since they're corresponding sides of congruent triangles.

Answer:
equivalent price/ gallon = 13.98 US$ / gallon
Step-by-step explanation:
Assuming that the exchange rate is 1.762 US$ /€ , then
thus
equivalent price/ gallon = liters/gallon * euros / liter * dollars/euro
equivalent price/ gallon = 3.78541178 liters/ gallon * 2.096 € /liter * 1.762 US$ /€ = 13.98 US$ / gallon
equivalent price/ gallon = 13.98 US$ / gallon
if the actual price would be different from the equivalent , then there would be an arbitrage opportunity ( profit with no risk)
Answer:
134 degrees
Step-by-step explanation:
a triange has a total of 180 degrees
this means the 2 angles in the are equal to
180-(last angle)=x+102
the exterior angle is also 180-(last angle)
thus you can set the two equal to each other
(4x+6)=x+102
move 6 and x
3x=96
x=32
plug in
(4(32)+6)=134
to check
180-134=46(last angle of the triangle)
32+102+46=180 (true)
