ANSWER
Transitive property of equality.
EXPLANATION
According to the transitive property of equality,
if
a=b and b=c, then a=c.
Therefore,
if x=y and y=10, then x=10 is an example of transitive property of equality.
Answer:
a = 6, b = -2, c = 3
Step-by-step explanation:
6x² - 2x + 3 = 0
a = 6, b = -2, c = 3

The shown pair of angles are Co interior angle pair, therefore the sum of those angles is 180°






The required value of x is 7°
