Question

if AB=2AC find BC And plz plz plz plz plz plz plz plz plz plz plz say the answer​

Answer 1

In right triangle ADC, angle ADC = 90°,

angle CAD = 60°

tan(CAD) = tan60° = CD/AD

√3 = CD/100

CD = 100√3 ... (i)

Now,

In right triangle ADB, angle ADB = 90°,

angle BAD = 60°

cot(BAD) = cot60° = AD/BD

1/√3 = 100/BD

BD = 100√3 ... (ii)

BC = CD + BD = 100√3 + 100√3 = 200√3

Hence, BC = 200√3 m.
