Answer 1

Step-by-step explanation:

for the 2 lines to be parallel the angles of crossing the third line must be equal.

and it is a given for 2 crossing lines, that the right top angle is equal to the left bottom angle, and the left top angle is equal to the right bottom angle.

therefore, the 2 indicated angles must be equal :

3x + 48 = 6x

48 = 3x

x = 16
