Let the length of one of the diagonals be 2x and the other be 2y, then
cos (76/2) = x/10
x = 10 cos 38 = 7.88 cm

sin (76/2) = y/10
y = 10 sin 38 = 6.16 cm

Plot of land between two roads are laid out according to the boundaries shown. The boundaries between the two roads are parallel
FinnZ [79.3K]
Given: 
                Cheshire Road           Shelby Road
Plot 1           40 yards                       48 yards
Plot 3                x                                56 yards


To solve for x, we get the ratio and proportion of both plots.

40/48 = x/56

Do cross multiplication.

40 * 56 = 48 * x
2,240 = 48x
2,240/48 = 48x/48
46.67 = x

Plot 3 of Chesire Road measures 46.67 or 46 2/3 yards.  Choice A.
