The length C B to the nearest tenth is 6.1
The length AC to the nearest tenth is 16.2
What is the length to the nearest tenth?
Length CB
tan 22° = opposite / adjacent
tan 22° = x / 15
15 × tan 22° = x
x = 15 × 0.4040
x = 6.06
Approximately, 6.1
Also,
AC² = AB² + CB²
= 15² + 6.1²
= 225 + 37.21
AC² = 262.21
AC= √262.21
AC = 16.2
