Step-by-step explanation:
Let U=universal set
C=students who drink coke
P = students who drink pepsi
<u>x = 9</u>
Step-by-step explanation:
mean = 5+7+7+x /4 = 7
19+x / 4 = 7
19+x = 28
x = 9
Based on the reflexive property of congruency, the missing step in the proof is: A. ∠ABC ≅ ∠DBE
<h3>What is the
Reflexive Property of Congruency?</h3>
The reflexive property of congruency states that an angle will always be congruent to itself.
In the diagram given, we can prove that ∠ABC ≅ ∠DBE based on the reflexive property.
Therefore, the missing step in nthe proof is: A. ∠ABC ≅ ∠DBE

Answer:
(–1, 1) and (4, –2)
Step-by-step explanation:
we know that
The vertex of the right angle of the triangle could be situated at a point with the same x-coordinate of point A and the same y-coordinate of point B or at a point with the same x-coordinate of point B and the same y-coordinate of point A
we have
A(4, 1) and B(–1, –2)
so
a point with the same x-coordinate of point A and the same y-coordinate of point B is the point (4,-2)
a point with the same x-coordinate of point B and the same y-coordinate of point A is (-1,1)
therefore
(–1, 1) and (4, –2)
