- In Right angled ∆ABC,∟BAC= 90°,∟B: ∟C = 1:2 andAC= 4cm.calculate thelenght of BC

'* Solution''''*
in some special right angled triangle

whose angle ratio 1:2:3 that is 30-60-90

has their sides ratio 1: :2

in ▲ABC, BC = 2. AC

BC = 2.4

BC = 8 cm

- A door of width 6 mt has an archabove it having aheight of 2 mt , find the radius if the arch
- The sides of a right angled triangle are in an AP. Show that sides are in ther ratio 3:4:5
