Answer:

d. 18

Step-by-step explanation:

Lengths AG and CF of the parallelogram are equal.

i.e AG = CF

where AG = 2x + 10

CF = 5x -2

→ 2x + 10 = 5x-2

(collecting like terms): 5x - 2x = 10 + 2

→ 3x = 12

x=12÷3 = 4

∴ CF = 5x -2 = 5(4) -2 = 20 - 2 = 18

∴ CF = 18 (answer)

dolphi86 [110]

1foot = 0.305m
50feet = 15.24m
9feet = 2.7m

Let the angle = x

According to SOHCAHTOA,

Tan x = opposite/adjacent

Tan x = 2.7m/15.24m = 0.177

Hence x = tan^-1 (0.177)

x = 10.03 degrees
