Answer:
Step-by-step explanation:
both sides are the same length so 20+6x+3=18+7x+2
all you have to do is get the variables and non-variables on opposite sides of the equation so 3=x

It's impossible because there is no "N" point in rectangle JKLM.
Answer:
135
Step-by-step explanation:
Okay so we know that all angles in tringle sums up to 180
Therefore ∠2 = 180 - ∠1 - ∠3 = 180 - 35 - 100 = 45deg
We also know that angles on a straight line add up to 180deg as well
Therefore ∠4 = 180 - ∠2 = 180 - 45 = 135deg
