Question

at a distance of 30 M away from the tower the angle of elevation of top of the tower is 30 degree find the height of the tower

Answer 1

in triangle,
tan 30 degree =height/30
1/root 3 = height/30
height= 30/root 3
height= 10 root 3
 

Answer 2

Answer:

$we \: know that \: b \: is \: 30m \\ and \: angle \: is \: 30 degree \\ so........\\ \tan(30 {}^{o} ) = p \div 30 \\ \\ 1 \div \sqrt{3 } = p \div 30 \\ on \: doing \: cross \: multiplication..... \\ \sqrt{3} p = 30 \\ so \: .. \\ p = 30 \div \sqrt{3} \\ on \: rationalizaing \: the \: root \: three \\ \: we \: get \: .. \\ \\ 30 \sqrt{3} \div 3 \\ = 10 \sqrt{3} m. \\ \\ \\ \infty \infty hope \: it \: helps \: you \infty \infty$
