Steps:
(n-2) * 180 = sum of interior angles
(3-2) * 180 = 180
Bottom Triangle
25 + 51 + x = 180
x = 104
Top Triangle
104 + 34 + x = 180
x = 42
Answer:
42
Add the amount of choices, and divide by the number of customers surveyed.
40 + 32 + 8 + 20 = 100
40 customers were surveyed
100/40 = 2.5
The average number should be D) 2.5
hope this helps
Answer:
The reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
Step-by-step explanation:
Definition of Reflexive Property of congurence
The meaning of Congruence is figure has the same size and shape. If you were comparing something to itself, then it definitely have the same size and shape this is called Reflexive Property of congurence .
By using Reflexive property of congurence .
RST = RST
Therefore reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
