Question

Find the missing side of triangle​

Answer 1

• Perpendicular=P=21
• Base=B=?
• Hypotenuse=H=29

Using Pythagoras Theorem

`\\ \sf\longmapsto B^2=H^2-P^2`

`\\ \sf\longmapsto B=√(H^2-P^2)`

`\\ \sf\longmapsto B=√(29^2-21^2)`

`\\ \sf\longmapsto B=√(841-441)`

`\\ \sf\longmapsto B=√(400)`

`\\ \sf\longmapsto B=20`
