Best ResponseYou've already chosen the best response.03x9=90 solving for x gives x=33 making the second one 40 degrees

Best ResponseYou've already chosen the best response.0That is if that 3x9 is the angle of the vertical line to the ground and the angle is "right"

Best ResponseYou've already chosen the best response.0@bcdrane42 Would it be correct to write: 3x  9 + x + 7 = 90 because perpendicular lines meet to form right angles and right angles have a measure of 90. There's one more theorem that goes with that.

Best ResponseYou've already chosen the best response.0Well you have to combine the 3x9 and x+7 = to 90 3x9+x+7=90 combine like terms 4x=92 Divide to get x by itself x=23 Then plug that back into x to get the two other angles.

Best ResponseYou've already chosen the best response.0so i would go 3*239 = 60 23+7=30

Best ResponseYou've already chosen the best response.0Actually it looks like 3x9 represents the angle between the vertical line and the 2ND LINE, not the ground. That would make what directx says correct: 3x9+x+7=90 solving for x gives you: 23

Best ResponseYou've already chosen the best response.0right angels give you 90 derees so it should add up to 90 degrees
