Question

find the length of $overline{ac}$. use that length to find the length of $overline{cd}$. what is the length of $overline{cd}$? round to the nearest tenth. 2.3 cm 4.0 cm 10.7 cm 18.6 cm

Explanation:

Step1: Find AC using sin(30°)

AC = AB × sin(30°) = 10 × 0.5 = 5 cm

Step2: Find CD using tan(25°)

CD = AC / tan(25°) ≈ 5 / 0.4663 ≈ 10.7 cm

Answer:

C. 10.7 cm
