A Google or Bing search box can be your friend, if you don't have a calculator with inverse trig functions. Most calculators that have trig functions also have the inverse functions, usually after a 2nd or "shift" key. Often, there is a mode setting for degrees or radians.

arcsin(0.33) ≈ 19°
arccos(0.47) ≈ 62°
arctan(1.21) ≈ 50°
arcsin(0.82) ≈ 55°

Answer:

435 ft

Step-by-step explanation:

area of triangle:

A = (b x h) : 2

A = (15 x 4) : 2

A = 60 : 2

A = 30 ft

area of rectangle:

A = b x h

A = 25 x 15

A = 375 ft

area of the yard = area of the triangle + area of the triangle + area of the rectangle (Here, both triangles have the same area.)

area of the yard: 30 + 30 + 375 = 435 ft.

So, the area of the yard is 435 ft.

I hope this was helpful. :)
