Step-by-step explanation:

Answer 2

Answer

The value of BC is 15√3 cm.

Step by step explanation:

Given,

Here ABC is a triangle

AB is perpendicular and BC is base and AC is hypotenuse

This is a right angle triangle,

.Tan30°=AB/BC

1/√3=15/BC

BC=15√3

By Pythagoras theorem we can also find length of AC

$AC² = AB² + BC²$

Here we have to put value of AB and BC then we will get value ofvAC.

Therefore value of BC is 15√3 cm.
