1/5( 5/2 x 4/7 -11/7) + 3/28

Multiply the terms (5/2 x 4/7) in bracket then subtract it from 11/14. Result will be 10/7.

Then multiply 1/5 with 10/7. The result will be 2/7.

2/7 + 3/28 = 11/28

Answer:

469.42 ft²

Step-by-step explanation:

Law of sines;

w/sin27 = 38/sin40

w = sin27*38/sin40

w = 26.84 ft

Angle x;

∡X = 180 - 27- 40 = 113º

Area;

A = 0.5*(26.84)*(38)*sin(113)

A = 469.42 ft²
