Answer:

30 degree

Step-by-step explanation:

So in this question, we take angle ABC as a straight line:

4x-30+3x=180 degree(linear pair)

7x-30=180 degree(by adding 4x and 3x)

7x=210 degrees (by adding 180 and 30 by taking 30 to the RHS)

x=30 degrees (by dividing 210 by 7 by taking 7 to the RHS)

Therefore, the value of x in the given fig. which will make ABC a line is 30 degree
