Chidi measured the angle of elevation of a tree and found it was 38°. He then
valked 25 m towards the tree and
measured the angle of elevation again
bo be 50°.
Find the actual height of the tree
d Find the total distance to the bot-
tom of tree from Chidi's initial
position
​

56.72 m, 72.6 m

Step-by-step explanation:

Given

The initial angle of elevation is

after walking 25 m, the angle of elevation is

In

In

From (i) and (ii)

The distance of tree bottom and Chidi's  is

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
