    Line segment AC is 10 m

    Step-by-step explanation:

    Step 1: This is a right triangle, so the trigonometric ratio tan can be used to find the length of AC. Given CB = 15 m and ∠BAC = 55°,

    tan 55° = opposite side/adjacent side = CB/AC = 15/AC

    ⇒ AC = 15/tan 55° = 15/1.43 = 10.50 m ≈ 10 m
