Question

in figure 1 abcd is a trapezium in which AB parellel DC,angle a=105 and angle b=115.find the value of x and y(hint a and b are top in figure x and y bottom in figure)

Answer 1

There fore x = 75 (at the left) and y = 65 (at the right)

Answer 2

x=75,y=65
angle a + x=180(allied angles)
llly angle b+y=180
