Question

in triangle abc ab is perpendicular to BC angle ACB is equal to 30 degree AB=15m then find the length of BC​

Answer 1

Answer:

the answer is 15√3 m pls... mark as brainliest

Answer 2

The length of BC is $15\sqrt{3}$ m .

Step-by-step explanation:

here, AB is perpendicular to BC

given AB = 15 m

$\anglr ACB = 30^\circ$

using the trigonometry

we find the base BC

Therefore,

in triangle ABC

$\tan 30^\circ =\frac{AB}{BC}$

$\frac{1}{\sqrt{3} }=\frac{15}{BC}$

$BC = 15\sqrt{3}$

hence , the length of BC is $15\sqrt{3}$ m .
