Answer:

144 ft^2

Step-by-step explanation:

Here we have a trapezoid with a triangle inside.

The legs of the trapezoid are 18 ft and 8 ft, and so the average length of the trapezoid is (18 + 8)/2 ft, o 13 ft.  The total area of the trapezoid is thus:

A = (13 ft)(16 ft) = 208 ft^2

Now we must find the area of the white triangle and subtract it from the area of the trapezoid already found.  The area formula for a triangle i

A = (1/2)(base)(height), which in this case is A = (1/2)(8 ft)(16 ft), or

A = 64 ft^2.

Subtracting the area of the triangle from that of the trapezoid yields

Area of figure = 144 ft^2

Step-by-step explanation:

1. Use the Pythagorean theorem to solve for side KM:

  • 16^2+KM^2=34^2
  • 256+KM^2=1156
  • KM^2=900
  • KM=30

2. Cosine is adjacent over hypotenuse, so cosine of M would be KM/34, or 30/34

3. Tangent is opposite over adjacent, so tangent of L will be KM/16, or 30/16

4. Sine is opposite over hypotenuse, so sine of M will be 16/34

5. KM=30, solved for in step 1.

hope this helps!!

Nataly_w [17]
Step one. create a common denominator.
ex. 15
walnuts = 10/15 dried fruit= 9/15

so if you had 15/15 pounds of dried fruit you would need 16/15 pounds of walnuts

which is 1 1/15 pounds of walnuts
