Question

Triangle PQR is an equilateral triangle having length of side as 10cm . find the height of triangle PQR​

Answer 1

Step by step explanation:

let ABC be the equilateral triangle of side 10 cm.

draw AD perpendicular to BC

AB = 10cm

AD = x

BD= 5cm ( since altitude of a equilateral triangle divides the base into equal halves)

AD^2 = AB^2 - BD^2

= 10^2 - 5^2

= 100-25

AD^2 = 75

Answer:

5√3 cm
