Best ResponseYou've already chosen the best response.0Good answerfrom watchmatch but alternatively see the problem as a ratio issue. The dividing line is parallel to the top line as the angles are equal as stated. Therefore... 20:30 = 35: 30 + x Multiply first ratio by a factor 7 and the second by a factor 4... 140:210 = 140: 4(30 + x) = 140: 120 + 4x Therefore equating RHSs 210 = 120 + 4x Subtract 120 from both sides 90 = 4x divide boith sides by 4 22.5 = x ...just a thought to consider.
