Answer:
Perimeter: 42cm
Area: 66cm^2
Step-by-step explanation:
Sum of all exterior angles = 360°
If each angle is 9°,
Number of sides = 360 ÷ 9
Number of sides = 40
-----------------------------------------------
Answer: Number of sides = 40
-----------------------------------------------
<span>z−7.8=32.9
add 7.8 to both sides
</span><span>z−7.8 + 7.8 = 32.9 + 7.8
simplify
z = 40.7</span>
"y = -cos x + 2" is the equation among the following choices given in the question that <span>represents the graph of y = cos x flipped across the x-axis then shifted vertically up by 2 units. The correct option among all the options that are given in the question is the first option. I hope the answer has come to your desired help.</span>
