Answer:

The first option is correct 7.1 cm

Therefore the length segment AC is 7.1 cm.

Step-by-step explanation:

Given:

In Right Angle Triangle DAC

∠A = 90°

∠D = 62°

CD = 8 cm = Hypotenuse

To Find:

AC = side opposite to angle D = ?

Solution:

In Right Angle Triangle DAC , using Sine Identity we have

[tex]\sin D = \dfrac{\textrm{side opposite to angle D}}{Hypotenuse}\\[/tex]

Substituting the values we get

[tex]\sin 62 = \dfrac{AC}{CD}\\\\0.8829=\dfrac{AC}{8}\\\\\therefore AC =7.063\approx7.1\ cm[/tex]

Therefore the length segment AC is 7.1 cm.
