It would be 16 π sq units!
Answer:
Triangle A prime B prime C prime. is obtained by dilating Triangle ABC. by a scale factor of 1 over 2. and then rotating it about the origin by 180 degrees
Step-by-step explanation:
All the coordinates of A'B'C' are -1/2 times those of ABC. The dilation factor is 1/2, and rotation by 180° is indicated.
A'(-1, -1) = (-1/2) × A(2, 2)
B'(-1, -5) = (-1/2) × B(2, 10)
C'(-4, -6) = (-1/2) × C(8, 12)
___
Rotation by 180° negates both coordinates. It is equivalent to reflection across the x-axis and reflection across the y-axis, in either order.
Answer:
21=x
Step-by-step explanation:
Those angles will add up to 180.
So make your equation 180=3x-3+5x+15
Add like terms, so 3x+5x=8x and -3+15=12
Now you have 180=8x+12
Subtract 12 from both sides, leaving you with 168=8x
Divide by 8 on both sides.
21=x
