All you have to do to calculate the mean average is add the values of the numbers together and then divide that sum by the number of numbers :D.
So in this case:
766 + 878 = 1644
1644 / 2 = 822
The average of these two numbers is 822.

Answer:
<em>Answer: SAS</em>
Step-by-step explanation:
We must prove that triangles ABC and EDC are congruent.
Since BD bisects AE, then AC is congruent with CE.
Since AE bisects BD, then BC is congruent with CD
Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.
Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.
Answer: SAS
