3x9=90 solving for x gives x=33 making the second one 40 degrees

That is if that 3x9 is the angle of the vertical line to the ground and the angle is "right"

3x9 is a right angle

@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.

Well 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.

so i would go 3*239 = 60 23+7=30

Actually 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

right angels give you 90 derees so it should add up to 90 degrees
