He original height of the leaning tower of pisa was 184 feet. at a distance of 140 feet from the base of the tower, the angle of elevation from the ground to the top of the tower is . how far is the tower leaning from the original vertical position?

Ans:; 

Let AB be the height of the leaning tower= 184 feet

Let AC be the distance from the base of the tower= 140 feet

Angle between BC and AC = 59 degrees

Applying the sine rule

AB/(Sin 59) = 140/(Sin B)

On cross multiplication we get, check image, 

37.3°

Explanation:

The angle of elevation can be found by using trigonometric tan function.

perpendicular is given by the height of the tower = 184 ft

base = distance from the tower = 140 ft

Thus, angle of elevation:

Now, the angle of elevation + angle made by tower from the original vertical position towards the ground = 180 -90

⇒Ф= 90° - 52.7° = 37.3°

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
