The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown. A trapezoid has a base of 3 inches, height of 1 inches, and top side length of 1 inch. What is the area of one trapezoidal face of the figure?

The area of one trapezoidal face is 2 square inch

Step-by-step explanation:

Area of a trapezoid is calculated as follows:

A = (a + b)/2 * h

where a, b and h are the lengths of the top side, the base and the height, respectively. Replacing with data:

A = (1 + 3)/2 * 1

A = 2 square inch

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

x
