Answer:
Option D.
Step-by-step explanation:
A reflection is a mirror image across the a line of reflection. The image will be perpendicular to the line of reflection and equal distance from it as the pre-image is too. This means that point G will move horizontally across the y-axis the same distance it is currently from the y-axis. It is 2 units away from the y-axis so G' will be 2 units on the other side or -2. This makes G' (-2,2). Notice this is the same coordinates of G only multiplied by -1. When reflecting a shape across the y-axis, the x-coordinates of the points are multiplied by -1.
So G (2,2) becomes (-2,2).
So F (-2,-1) becomes (2,-1).
So H (4,-3) becomes (-4,-3).
The answer is 20. Multiply 5/6 by 24 to get 20.
Sry I know my handwriting suck and also I accidently did them in the opposite order as listed but I hope this helps
answers:
20) R=-8
22) R=-2
24) X=6
Answer:
8.44 m
Step-by-step explanation:
SohCahToa is a good way to remember that Sin = opposite/hypotenuse, Cosine = adjacent/hypotenuse and Tangent = opposite/adjacent. In this case, we have to use tangent. So tan 37° = x/11.2. Multiply both sides by 11.2 and you get tan 37° × 11.2 = x; The height of the school is x so the height of the school is 8.44 m
Answer:
addition add 3 to both sides to isolate the variable term
