A
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to find EF
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
EF² + DF² = DE² ← substitute values
EF² + 12² = 18², that is
EF² + 144 = 324 ( subtract 144 from both sides )
EF² = 180 ( take the square root of both sides )
EF = → A
Answer: = (-2,3)
Step-by-step explanation:
- Rotation is a transformation of a figure by rotating it for a specific angle about a fixed point.
Here, fixed point = origin = (0,0)
Transformation rule for rotation of counterclockwise about the origin:
Then, the image of the point (3,2) = (-2,3)
Hence, the image of the point (3,2) after a rotation of counterclockwise about the origin = (-2,3)
