Answer:

16 + 2*pie

Step-by-step explanation:

perimeter of parallelogram : 4+8+4= 16

perimeter of a semicircle : 2*pie* r but it is semi circle so /2 radius is 4/2 which is 2 so 2*pie will give you the perimeter of your semicircle

perimeter of the shape 16 plus perimeter of the semicircle

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

law of exponent
PEMDAS

<h3>tips and formulas:</h3>

${x}^{ - y} < = > \frac{1}{ {x}^{y} }$
$( {x} ^{z} )^{y} < = > {x}^{y \times z}$

<h3>let's solve:</h3>

$( {3}^{3} . {6}^{6} {)}^{ - 3}$

$\frac{1}{( {3}^{3}. {6}^{6} {)}^{3} }$

$\frac{1}{ {3}^{3 \times 3}. {6}^{6 \times 3} }$

Is the point 3/5 and 4/5 corresponds to an angle in the unit circle what is the csc

Mariulka [41]

<u>Answer:</u>

csc = 5/4

<u>Step-by-step explanation:</u>

Assuming that the two given points 3/5 and 4/5 are the two sides of a triangle and a right angle 0 with legs x and y and z as its hypotenuse.

Then using Pythagoras Theorem:

$z^2=x^2+y^2$

$z^2=(\frac{3}{5} )^2+(\frac{4}{5} )^2$

$z^2 = \frac{9}{25} + \frac{16}{25}$

$z^2=\frac{25}{25}$

$z^2=1$

Taking square root on both the sides:

$z=1$

Now, $sin\alpha=\frac{4}{5}$

and we know that $csc = \frac{1}{sin\alpha }$

Therefore, csc = 5/4.

Exterior angles of a triangle. Please help. Due today

yulyashka [42]

Answer:

1) 140 2)68 3) 125 4) 140

Step-by-step explanation:

for these, because you're trying to find the angle from 180 degrees, you would subtract the angle on the 180 degree line from 180.

1) 180-40 = 140

2) 180-112 = 68

3) 180-55 = 125

4) 180-40 = 140

Hope this helps!
