Easy maths question I’ll give brainiest

Answer 1

Answer:

BC ≈ 12.6 m

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan31° = $\frac{opposite}{adjacent}$ = $\frac{AB}{BC}$ = $\frac{7.6}{BC}$ ( multiply both sides by BC )

BC × tan31° = 7.6 ( divide both sides by tan31° )

BC = $\frac{7.6}{tan31}$ ≈ 12.6 m ( to 3 sf )
