To prove it, Please follow the following steps. 1) Draw two triangles ABC  and Produce BC to D.  2) Measure < A  and < B ,and  fill in table. 3) similarly, measure the angle < ACD and fill in table given .....

Here, < ACB = <DAC = 64o  Because, AD // BC  and alternate angles. in triangle ABC, < ABC + x + <ACB = 180o  Because, sum of angles of a riangles is 180o. or, 60o + x + 64o = 180o Solve and get .....

To find the value of x, we can draw a line // to given as in figure, Now, you can see here, a = 40o  and  b = 50o  [ alternate angles ] Finally,   x  =  a + b =.........find the .....
