Answer:

C) 12.5

The length of BC = 12.5cm

Step-by-step explanation:

Step(i):-

Given that ΔABC

Given that AB = 15cm and ∠A = 40°

we will use trigonometric function

$tan x = \frac{oppositeside}{adjacentside}$

$tan 40^{0} = \frac{BC}{AB} = \frac{BC}{15}$

Step(ii):-

we know that tan40° = 0.83909

$tan 40^{0} = \frac{BC}{15}$

BC = 15 × tan 40°

BC = 12.58649

BC = 12.5cm

Final answer:-

The length of BC = 12.5cm
