Two buildings are 200m apart. From a point midway between them, the angles of elevation to the top of each building are 12o and 9o respectively. To the nearest tenth, how much taller is one building compared to the other?
I think that is supposed to be 12o and 9 o
For one building tan 9 = height1 / 100
for the other building tan 12 = height2 /100 Now you should be able to find their heights and the difference.....
