Answer:
<em />
55 degrees
<em />
Step-by-step explanation:
<em />
In the initial position, the angle of elevation of the 20 meter building to your feet is 45 degrees, that means that you are at 20 meters from the building (thus forming an isosceles triangle with with the building, with internal angles 456 degrees, 90 degrees, and 45 degrees.
<em />
When you walk 6 meters towards the building, you are now at 14 meters from it. Therefore you need to examine now another triangle where the angle is unknown but for which you know the opposite side (20 meters of the building's height), and the adjacent side (14 meters of your distance to the building). See image attached for more clarity on the picture you need to study.
<em />
The tangent of this new angle is defined as opposite side divided by adjacent (opp/adj) which in our case renders 20/14 = 10/7
<em />
So to find the angle, we need to apply the arctangent function to this value.
<em />
Therefore:
<em />
<em>new angle = arctan(10/7) = 55 degrees</em>

• To solve Questions of type 11 we need to simplify the equation by using mathematical operations !!
• To solve Questions of type ( 13 , 15 and 17 ) we try to make the bar numeral to come other side of decimal
° and by subtracting we get the required fraction !!
