Answer:the first option is the correct answer

Explanation:

Triangle ACD is a right angle triangle. Taking 62 degrees as the reference angle,

The opposite side is AC

The hypotenuse is DC = 8 cm

The adjacent side is DA

To determine AC, we would apply trigonometric ratio. It is expressed as

Sin# = opposite side / hypotenuse

Where # = 62 degrees. Therefore,

Sin 62 = AC/8

Cross multiplying

AC = 8Sin62 = 8 × 08829

AC = 7.0632

Approximately 7.1 cm
