Question 1185145: The base angles of a trapezoid are 34˚ and 48˚, respectively. If its upper and lower bases are 120m and 220m, respectively, compute the area of the trapezoid. (Hint: Get the h of the trapezoid by using the triangles on the side of the trapezoid).

If the two triangle ends (both as right-triangles) could be shuved together to get rid of the rectangular part, then there are

Left right triangle: leg x and y, angle opposite of y is 34 degree; angle opposite of x is 56 degree.
Right right triangle: leg 100-x and y, angle opposite of y is 48 degree, and angle opposite of 100-x is 42 degree.

The two triangles together form a segment of 220-120=100 meters; split into x and 100-x.

To find what is y, the HEIGHT of the original trapezoid:
-------------use this system to solve for y.
