The polygon circumscribes the circle. Which of the following is the perimeter of the polygon?
dolphi86 [110]

The perimeter of the polygon that circumscribes the circle is 78 cm

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The circle tangent theorem states that tangents which meet at the same point are equal in length. Hence:

The missing lengths are 8, 6, 9 and 16.

Perimeter of the polygon = 2(8) + 2(6) + 2(9) + 2(16) = 78 cm

The perimeter of the polygon that circumscribes the circle is 78 cm

Anyone know the answer?
yan [13]

Answer:

0.

Step-by-step explanation:

The angle whose sine is 5/12 = 22.62 degrees and in Quadrant II it is

180 - 22.62 degrees

The angle whose tan is (5/12)  = 22.62.

So we can write  α as 180 - α  and β as α.

sin (α+β) = sin ( 180 - α = α) = sin 180

= 0.
