The perimeter of the polygon is 53.6 units.
Solution:
The reference image to the answer is attached below.
AP = 8, BQ = 7.8 and CR = 11
AP and AR are tangents to a circle from an external point A.
BP and BA are tangents to a circle from an external point B.
CQ and CR are tangents to a circle from an external point C.
<em>Tangents drawn from an external point to a circle are equal in length.</em>
⇒ AP = AR, BP = BQ and CQ = CR
AR = 8
BP = BQ
⇒ BP = 7.8
CQ = CR
⇒ CQ = 11
Perimeter of the polygon = AP + BP + BQ + CQ + CR + AR
= 8 + 7.8 + 7.8 + 11 + 11 + 8
= 53.6
The perimeter of the polygon is 53.6 units.
Answer:
8
Step-by-step explanation:
This is a special right triangle with angle measures 90-60-30 degrees
The side lengths are like the following :
The side length that sees 90 degrees is represented with x
The side length that sees 60 degrees is represented with x
The side length that sees 30 degrees is represented with 2x
the side that sees 90 degrees is given as 16 so x = 8 and so a = 8
