Wind I think what are the choices?
Answer:
90 (angle in a semicircle)
The area of a regular hexagon is the 3 times the product of the apothem and side length.
22. 3*(6.1 m)*(7 m) = 128.1 m^2
23. 3*(11.3 in)*(13 in) = 440.7 in^2
24. 3*(9.5 ft)*(11 ft) = 313.5 ft^2
25. The area ratio is the square of the linear dimension ratio: (3/4)^2 = 9/16.
Subtract 20 from both sides to get -3x = 155. Divide both sides by -3. X = -51 2/3
