20+100X6+X

Video Solution

Solution Steps

00:00 Calculate X
00:03 Parallel lines according to the given data
00:08 Alternate angles between parallel lines are equal
00:12 Therefore the angles sum to 180 (supplementary to a straight angle)
00:16 Group terms and isolate X to find the solution
00:27 And this is the solution to the question

Answer
