see diagram.
1. Draw a horizontal line and mark AB of length 2.5 cm.
2. At A draw a line ALK ⊥ AB.
3. At B draw line BL at an angle 60° to AB, to cut ALK at L.
4. At L draw a horizontal line LM.
5. From A mark AK = 7.5 cm on the line ALK.
6. At K draw a line KM at 60° to KLA to cut LM at M.
Now ΔKLM has sides such that KL + LM + MK = 15 cm and ∠L = 90° and
∠M = 30°.
