Question

The diagram shows a wedge ABCDEF

BC=13cm

CF=6cm

FA=20cm

Calculate the length of AB

Answer 1

AB = 13.96 cm

Explanation:

I suppose your wedge like the picture attached, otherwise you can ajust the calculations by yourself

AC² = FA² - CF² = 400 - 36 = 364

AB² = AC² - BC² = 364 - 169 = 195

AB = √195 = 13.96
