Answer: THE SECONDED ONE
Step-by-step explanation: NONE
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:
53°
Step-by-step explanation:
x + (2x + 21) = 180
(Corresponding angles &
Supplementary angles)
3x + 21 = 180
3x = 159
x = 53°

Answer:
The frequency of rolling a 3 or a 6 would be the same even if you try thousands or millions times.
The probability of rolling a 3 is: 1/ total outcomes probability = 1/6
The probability of rolling a 6 is: 1/ total outcomes probability = 1/6
The probability of rolling a 6 or a 3 = 2/ total outcomes probability = 2/6 = 1/3
Therefore, if you rolling the cube 600 times, the probability of rolling a 3 or a 6 is still 1/6. If 3 and 6 are both allowed, the probability would become 1/3
Hope this helped :3
