Have you tried looking the answer up?
The answer is B (100 times).
Answer:
∠A ≈ 71.57
Step-by-step explanation:
<em><u>You use inverse tangent since it gives you the opposite and adjacent sides: </u></em>
≈ 71.565
<em><u>Round to nearest hundredth:</u></em>
≈ 71.57
- Reflection about the y-axis has rule (x,y)→(-x,y);
- Reflection about the x-axis has rule: (x,y)→(x,-y).
Consider rectangle ABCD and select, for example point A(-5,1).The set of reflections about the y-axis, x-axis, y-axis, x-axis will act on A in following way:
- about y-axis A(-5,1)→A'(5,1);
- about x-axis A'(5,1)→A''(5,-1);
- about y-axis A''(5,-1)→A'''(-5,-1);
- about x-axis A'''(-5,-1)→A(-5,1).
This reflections act on all rectangle vertices in the same way, then
the set of reflections that carry rectangle ABCD onto itself is
y-axis, x-axis, y-axis, x-axis
