Question

In this figure, the quadrilateral is circumscribed about the circle. Find the perimeter of this polygon.

74 cm

76 cm

78 cm

80 cm

Answer 1

Answer:

  78 cm

Step-by-step explanation:

The missing side lengths are the same as the side lengths shown, so the perimeter is double the sum of the given measures.

  2(8 +16 +9 +6) cm = 78 cm

__

Both of the tangents to a circle from an external point (quadrilateral vertex) are the same length.

Answer 2

Answer:

78

Step-by-step explanation:

from the image

x = 9

y = 16

L = 6

z = 8

because each two are tangents to the circle from the same point

the perimeter = 78 cm
