We can calculate this by first finding a side length, s ....we have
43.3 = (1/2) s^2 (sin 60) =
43.3 = (1/2) s^2 (√3/2) mutiply both sides by 4/√3
(43.3)(4/√3) = s^2 take the square root of both sides
s = about 10
So the altitude is (10/2)√3 = 5√3 = about 8.66 linear units
Check...... (1/2)bh = (1/2)(10)(5√3) = about 43.3
