Answer:
B) 102°
Step-by-step explanation:
Reflection is an example of transformation in which a given image is flipped over a reference line which changes the orientation of the figure, but not its length and shape. A rotational transformation is formed by two reflections.
In the given question, image ABCD is reflected over lines I, then m at an angle of 51° to each other. Since rotation is twice the acute angle with respect to the center of rotation, therefore ABCD rotates through an angle of 102°.
Answer:
2060.63 m (2061 to the nearest metre).
Step-by-step explanation:
4065^2 = 3504^2 + x^2 where x is the horizontal change.
x^2 = 4065^2 - 3504^2
x^2 = 4246209
x = √(4246209)
= 2060.63 m.
