What is the length of BC in right traingle ABC if AD is peroendicular to BC and AD=4 and BD=6
TG Team 26/10/2018 12:42 pm
Alternative approach :
AD^2 = BD x DC
4^2 = 6 x DC
DC = 16/6 = 8/3
AC = AD + DC = 8/3 + 6 = 26/3

In equilateral triangle ABC with side 16. If ADis perpendicular to BC and AE is congruent to ED then BE=?
TG Team 27/10/2018 12:11 pm
AD ( Altitude of the triangle ) = AB sqrt{3}/2
AD = 16sqrt{3}/2 = 8sqrt 3
AE = ED = 4 sqrt{3}
BE = sqrt { DE^2 + BD^2 } = sqrt {[ 8^2 + 4(sqrt3)^2 ]
