Answer 2

Answer:

$\fbox{Given}$

➝ equilateral triangle with side 8 cm

$\fbox{to \: find}$

➝ height of the triangle.

$\fbox{solution}$

In the given ∆ ABC , AD is the height of the triangle.

♠️ AD the height of the ∆ ABC is perpendicular to BC.

so, AD bisect BC

• BD= DC

consider ∆ ADC

by applying Pythagoras theorem we get,

➝ AC²= AD²+DC²

➝ AD²= AC²- DC²

➝AD²= 64- 16= 48

➝AD²=√48

➝AD=√48

➝AD= 6.9 cm
