2. What is the area of each cut surface 3. What is the total area janey still needs to paint? Explain how you found your answer

9514 1404 393

Step-by-step explanation:

1. The shape of each cut surface is the same shape as the base it is parallel to: a rectangle. It is an 8" by 10" rectangle.

__

2. The area of each cut surface is the area of the rectangle:

  A = LW = (10")(8") = 80 square inches

__

3. The total area of cut surfaces is the sum of the two areas on either side of the cut:

  new surface area = 2 × 80 square inches = 160 square inches

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
