Because ABCD is an isosceles trapezoid, the angles A and D are congruent.
BA and CD are congruent (given) and AD is congruent to itself (reflexive property).
Then triangles BAD and CDA form a pair of SAS triangles, so they are congruent.
BD and CA are corresponding parts in those triangles, so they are congruent (CPCTC).

Answer: x = 9
Step-by-step explanation:
15 / 20 = (2x + 3) / 28
cross multiply
15(28) = 20(2x + 3)
420 = 40x + 60
360 = 40x
x = 9
This is a sampling technique used when natural groupings are evident in a statistical population. It is often used in marketing research.
Area of circle = 3.14 x 6^2 = 3.14 x 36 = 113.04
1/2 circle = 113.04 / 2 = 56.52
Area of rectangle = 8 x 6 = 48
Area of figure = 48 + 56.52 = 104.52
answer
104.52 ft^2
