Answer 1

Answer:

AB = 5.6 cm

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 62°

Hypothenus = BC = 12 cm

Adjacent = AB =?

The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:

Cos θ = Adjacent / Hypothenus

Cos 62 = AB / 12

0.4695 = AB / 12

Cross multiply

AB = 0.4695 × 12

AB = 5.6 cm

Thus, length AB is 5.6 cm
