Answer:
19.51 units = x
Step-by-step explanation:
Here is one way :
Height = 18 cos 47 = 12.276
then cos 51 = 12.276 / x
x = 12.276 / cos 51 = 19.51
Are 3/9 and 2/3 equivalent

Answer:
B
Step-by-step explanation:
Reflection is a transformation that preserves lengths.
Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.
This means that corresponding sides have the same lengths:
- XY = X'Y' = 7 in;
- XZ = X'Z' = 4 in;
- YZ = Y'Z' = 5 in.
Find the perimeters of both triangles:
Hence, only option B is true.
