Question

Find the missing side . round the the nearest tenth

Answer 1

`S(O)/(H) C(A)/(H) T(O)/(A)`

`Sin=(Opposite)/(Hypotenuse) Cos=(Adjacent)/(Hypotenuse) Tan=(Opposite)/(Adjacent)`

7) You have the opposite. You need the adjacent.

`Tan=(Opposite)/(Adjacent)`

`Tan57=(12)/(x)`

`x=(12)/(Tan57)`

x = 7.79289... =

7.8

8) You have the hypotenuse. You need the Opposite.

`Sin=(x)/(Hypotenuse)`

`Sin37=(x)/(13)`

x = sin37 × 13

x = 7.8235... =

7.8

9) You have the hypotenuse. You need the opposite.

`Sin=(x)/(Hypotenuse)`

`Sin59=(x)/(11)`

x = sin59 × 11

x = 9.4288.... =

9.4

10) You have the hypotenuse. You need the opposite.

`Sin=(x)/(Hypotenuse)`

`Sin53=(x)/(11)`

x = sin53 × 11

x = 8.7459.... =

8.7
