Emily wants to buy a square tablecloth to cover a square card table. she knows the tabletop has an area of 9 square feet. what are the minimum dimensions of the tablecloth emily needs? [ ] feet by [ ] feet.

3 ft by 3 ft

Step-by-step explanation:

The minimum dimensions will be those of a square with an area of 9 ft².

The formula for the area of a square is

A = l²     Substitute the area

9 = l²     Take the square root of each side

l = 3

The minimum dimensions are 3 ft by 3 ft.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer:

your answer is: c. 196 7/8 in^3.
