That's false. RX, SX, and RS may be the sides of an isosceles triangle.
Answer:
1/3
Step-by-step explanation:
Half of two of something would be only one of that something. In this case the something is 1/3 so our answer is 1/3.
Sum of interior angles of a quadrilateral = 360 degrees.
x + 10 + x + 10 + 2x + 50 + 2x + 50 = 360
6x + 120 = 360
6x = 360 - 120 = 240
x = 240/6 = 40
x = 40
A = D = 2(40) + 50 = 80 + 50 = 130 degrees
B = C = 40 + 10 = 50 degrees
Exact Form: -3/2
Mixed number form: -1 1/3
The area of the trapezoid would be 5/8 ft squared.
