Please answer this question now now correct

Answer

469.42~ ft^2

Explanation

The area of a triangle can be obtained using a formula

1/2absinC

Angle C being YXW is the easiest to work with for reasons revealed later (when using sine rule)

To obtain this angle:

180 - 40 - 27 = 113

Now, you have to use the Sine Rule

Side a/sin (angle A) = Side b/sin (angle B) (or inverse)

38/sin40 = side b/sin 27

Side b = 38/sin40 • sin27

Side b = 26.84~ ft

Since you now have side b and side a as well as angle C (worked out earlier, you can use the formula

1/2absinC

1/2 • 38 • 26.84 • sin(113)

= 469.42~ ft^2

Could you make it more clear?
