The measure of the angle formed by two intersecting perpendicular lines is . choices; . 45. 360. 180. or . none of the above

The correct answer is ‘‘none of the above’’.

Step-by-step explanation:

The angle formed by perpendicular lines is 90 degrees. According to the definition of perpendicularity, two lines are perpendicular if they meet at a right angle.

The definition of ‘‘right angle’’ tells us that the measure of a right angle is 90 degrees.

It is not difficult to deduce that the other three angles have the same measure. Then, two perpendicular lines form four right angles.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
