Quadrilateral

Step-by-step explanation:

The sum of the interior angles of a quadrilateral are equal to 360`. To find the fourth angle of a quadrilateral when the other three angles are known, subtract the number of degrees and the other three angles from 360` (I can't put the circle on a Samsung computer ;^;)

Find the perimeter of this figure. Please show work. ​
Elena-2011 [213]

Answer:

  40.56 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the "sides" of this figure. Starting from the left side and working clockwise, the sum is ...

  P = left side (8 ft) + top side (10 ft) + semicircle (1/2×8 ft×π) + bottom side (10 ft)

  = 28 ft + 4π ft

  = (28 +12.56) ft

  P = 40.56 ft
