I think it’s B but I dint really know
Answer:
8
Step-by-step explanation:
its 8 because u divided the 1x12 and that = 8
Answer:
The ratio for sin(X) is 
The ratio for cos(X) is 
Step-by-step explanation:
- The ratio of the sine of a right triangle is:
Since we need the ratio for angle X, 
. From the picture we can infer that the opposite side of X is 
. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:
- The ratio of the cosine is:
Similarly, , adjacent side = 5, and hypotenuse = 12, so
Answer:
D. (x, y) → (x, −y)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.
The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.
The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.
The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.
The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.
