Answer:
Rational
Step-by-step explanation:
2.4 is a terminating decimal
rational
since rational numbers include both negative,positive , positive decimals negative and positive decimals, fractions..
A(-4, 5) => A'(-4+2, -5) = A'(-2, -5)
B(-6, -4) => B'(-6+2, -(-4)) = B'(-4, 4)
C(4, -4) => C'(4+2, -(-4)) = C'(6, 4)
Hence the new coordinates are A'(-2, -5), B'(-4, 4) and C'(6, 4).
Given that the angle is located in Quadrant II; and
In Quadrant II, x is negative and y is positive.
To find , we first determine the opposite angle of .
This will be done using the Pythagoras theorem.
Therefore:
