1.1.4 Worked Example
- 3. So if
sin = opposite/hypotenuse
35 =CB
sin 9
rearrange the equation:
(sin 35) × 9 = CB
Using your calculator:
5.16 m = CB
- 4. So if
cos = adjacent/hypotenuse
AC
cos 35 = 9
rearrange the equation:
(cos 35) × 9 = AC
Using your calculator:
7.37 m = AC
- 6. So if
tan = opposite/adjacent
y = AC
tan BC
y = 7.37
tan 5.16
y = 55o
