Dana is attaching a shelf to a wall and needs the shelf to be perpendicular to the wall. How many degrees should the shelf be relative to the wall?

The shelf should be 90 degrees relative to the wall.

Perpendicular lines are described as two lines that meet or intersect each

other at right angles (90°) . This simply means the lines form a 90 degree

angle.

Dana is attaching a shelf to the wall and she needs the shelf to be

perpendicular to the wall.

Therefore, for the shelf to be perpendicular to the wall, the angle of the shelf

relative to the wall should be 90 degrees.

The shelf must be at right angles (90 degrees) relative to the wall.

Step-by-step explanation:

Dana concern is that the shelf must be perpendicular to the wall. This means that the angle between the wall and the Dana’s shelf must be 90 degrees.

The term “perpendicular” is sometimes used in the mathematical terminology for the angle of 90 degrees. Hence, the Dana’s shelf must be at 90 degrees relative to the wall.  It is to be noted here that straight lines make an angle of 180 degrees. Since the shelf is at 90 degrees, either side of the shelf would be at 90 degrees to the wall.

40% success vs 60% fail

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
