Question
In what ratio does point$\Big(\frac{24}{11},\text{y}\Big)$ divide the line segment joining the points P(2, -2) and Q(3, 7)? Also, find the value of y.
✓
Answer
Let PA : AQ = k : 1
$\therefore \frac{2 + 3\text{k}}{\text{k + 1}} = \frac{24}{11}$
$\Rightarrow \text{k} = \frac{2}{9}$
Hence the ratio is 2 : 9.
Therefore $\text{y} = \frac{-18 + 14}{11} = \frac{-4}{11}$

Roshani saw an eagle on the top of a tree at an angle of elevation of 61°, while she was standing at the door of her
house. She went on the terrace of the house so that she could see it clearly. The terrace was at a height of 4m. While
observing the eagle from there the angle of elevation was 52°. At what height from the ground was the eagle ?
