When a ladder of length 2.5 m leans against the of 55° with the ground. When the ladder leans
top edge of a window of a building, it forms an
angle
against the lower edge of the same window,
it forms an angle of 38° with the ground. Find the
height of the window, giving your answer in
centimetres.

 window = 0.50 m

Step-by-step explanation:

First, draw a picture (see image below).

Then set up two equations that eventually you can set equal to each other.

Given: Ladder (hypotenuse) = 2.5

           Angle to Top edge of window = 55°

          Angle to Lower edge of window = 38°

         

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
