Mathematics

Kamila [148]3 years ago

Answer:

AC ≈ 5.3 ( to the nearest tenth )

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos68° = \frac{adjacent}{hypotenuse} = \frac{AB}{AC} = \frac{2}{AC}

Multiply both sides by AC

AC × cos68° = 2 ( divide both sides by cos68° )

AC = \frac{2}{cos68} ≈ 5.3

Answer:

5.3

Step-by-step explanation:

Cos(68) = adjacent/hypotenuse

Cos(68) = 2/AC

AC = 2/cos(68)

AC = 5.3389343253

AC = 5.3
