Enter T or F depending on whether the statement is true or false. (You must enter T or F  True and False will not work.) 1. A plane and a line either intersect or are parallel
2. Two planes orthogonal to a third plane are parallel
3. Two lines either intersect or are parallel 4. Two lines parallel to a third line are parallel 5. Two planes parallel to a third plane are parallel . Two planes parallel to a line are parallel . Two lines parallel to a plane are parallel . Two lines orthogonal to a plane are parallel GDW‘IO’) . Two planes either intersect or are parallel
10. Two planes orthogonal to a line are parallel 11. Two lines orthogonal to a third line are parallel e (1 point) Match the equations of the plane with one of the graphs below. 1.a:+y:2

they discovered that the ground had tilted so that measurements of 3 points on the ground gave coordinates
of (0,0,0), (2, 2, 0), and (O, 2, 2). By what angle does the tower now deviate from the vertical? radians. @ (1 point) The axis of a light in a lighthouse is tilted, but the light shines perpendicular to
its axis. When the light points east, it is inclined upward at 7 degrees. When it points
north, it is inclined upward at 7 degrees. What is its maximum angle of elevation? Answer = degrees ...
