**Problem**

Two men facing a tall building notice the angle of elevation to the top of the building to be 30

^{o}and 60

^{o}respectively. If the height of the building is known to be

*h*=120 m, find the distance (in meters) between the two men.

Heuristic Problem Solving

**Stage 1**

**Question any assumptions**

Key in your assumption/s in the linoit individually.

**Stage 2**

**Solve the Problem Individually (my perspective)**

Once your assumptions and hypothesis have been clarified, start working on the problem individually. No discussion with anyone for this stage.

**Stage 3**

**Collaboration - seeking multiple perspectives**

In the big group of 5-6 students, present and discuss your solution with the group.

Focus on the assumptions/hypothesis, Process and the validity of the final solution(s).

Post your Group's solution as a New Post with the following criteria:

Post Title: Heuristic Solution (Group number)

Present the following:

- Assumptions Made

- Process (how you solved the problem) - what method/approach you used eg diagrams, on-line resources

- Final Solution

**Stage 4**

**Peer Assessment**

Review the solution(s) from other groups.

To facilitate process, follow the following:

Group 1 to comment on Group 2

Group 2 to comment on Group 3

Group 3 to comment on Group 4

Group 4 to comment on Group 1

**Stage 5**

**Self Assessment**

Review the comments made by the other group.

Be prepared to defend or justify your POV.

However, if an error has been committed - learn from it.
