Answer: Option c.
Step-by-step explanation:
The missing figure is attached.
Given a point
:
1. If it is reflected over the y-axis:
→ 
2. If it is reflected over the x-axis:
→ 
3. If it is rotated 180 degrees about the origin:
→ 
In this case, you can identify that the point A is:

Then:
If it is reflected over the y-axis:
→ 
If then it is reflected over the x-axis:
→ 
Finally, if this is followed by a rotationf of 180 degrees about the origin, this is:
→ 
15 50
---- = ----
x 60
(15*60)/50
900/50
18
It takes the ostrich 18 minutes to run 15 miles.
You have to combine like terms.

Answer:
19,463 cm²
Step-by-step explanation:
The area is given by the formula ...
A = (1/2)ij·sin(K)
Filling in the values, we find the area to be ...
A = (1/2)(270 cm)(170 cm)·sin(122°) ≈ 19,463 cm²
