Answer:

C. Only her Perimeter is Correct

Step-by-step explanation:

12x3= 36

17x2= 34

13+5=8

36+34+8= 88

The area would be around 365.

WILL MARK THE BRAINLIEST!! What are the amplitude, period, phase shift, and midline of f(x) = 2 sin(x + π) − 4?
xxMikexx [17]

Answer:

Step-by-step explanation:

Amplitude is twice the coefficent of the sine function. In this case, 2*2=4

Period is 2\pi divided by the coefficent of x, in this case, \frac {2\pi} 1 =2\pi

Phase shift, is how much you sum or subctract from x inside the sine, in this case \pi.

Midline you get by hiding the sine and reading what's left, in this case, -4.

given that interior angle of a regular polygon is five times of its exterior angle, calculate the size of interior angle of the
Natali5045456 [20]

Answer:

Step-by-step explanation:

Let the exterior angle = x

Interior angle = 5x

x + 5x = 180   { interior angle and exterior angle are linear pair}

6x = 180

x = 180/6

x = 30

Interior angle = 5*30 = 150
