We use Pythagoras theorem here
Angle of elevation = hypotenuse
if hyp = 60 nd perpendicular = 10
first we have to calculate it's bas
Now we have to find perpendicular so that,
Again we will use Pythagoras theorem ,

Step-by-step explanation:
Let the height be EC
Let the the angle EAD be 45° and the angle EBC be 60°
Let EB be x m and in reactangle ABCD we know that opposite sides are equal: AB = CD = 10 m and BC = AD
Now,
