Answer:
Step-by-step explanation:
Given:
Number of people to be seated should be greater than 75.
Let be the number of people. So,
Now, there is a single private chef's table that can seat 3 people.
Tables bought by the owner =
Number of people seated in 1 table = 4
So, number of persons that can be seated in tables =
Now, total number of persons that can be seated in these two types of tables is the sum of 3 and
Therefore,
But,
Hence, the inequality to show the situation is:
<u>Answer-</u>
<em>The correct answer is</em>
<em>∠BDC and ∠AED are right angles</em>
<u>Solution-</u>
In the ΔCEA and ΔCDB,
As this common to both of the triangle.
If ∠BDC and ∠AED are right angles, then
Now as
∠BCD = ∠ACE and ∠BDC = ∠AED,
∠DBC and ∠EAC will be same. (as sum of 3 angles in a triangle is 180°)
Then, ΔCEA ≈ ΔCDB
Therefore, additional information can be used to prove ΔCEA ≈ ΔCDB is ∠BDC and ∠AED are right angles.
