Find the length of side AB. Give your answer to 1 decimal place.
ehidna [41]

Answer:

Length of side AB = 5.6 cm

Step-by-step explanation:

From the figure attached.

In right triangle ABC,

m∠ABC = 62°

m(BC) = 12 cm

By applying Cosine rule in this triangle,

Cos62° = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

Cos62°= \frac{AB}{BC}

0.46947 = \frac{AB}{12}

AB = 12 × 0.46947

AB = 5.63

     ≈ 5.6 cm  

Therefore, length of side AB = 5.6 cm
