Rosa:And one example trigonometric related to real-life situations?
Miss Sarah:Okay okay, let me explain
Opposite

Miss Sarah:Example if there is no b then we have to follow the formula on the board which means b = root c the power of 2 - a the power of 2
?
b
5
Hypotenuse
O
b =
c =
Miss Sarah:so b = root 5 to the power 2 - 4 to the power 2 when it has been raised to the root 25 - 16 is subtracted from the root 9 and the last result is 3
a =
c

Miss Sarah:Trigonometry can be used to roof a house, to make the roof inclined ( in the case of single individual bungalows), measuring tree and the height of the roof in buildings etc. This is an example.
Nicky, Rosa, Bryan:Oh I see
