Answer:
The altitude = 4.8 answer B
Step-by-step explanation:
∵ The altitude is ⊥ to the longest base from the shortest base
∵ The diagonal = 12
∵ Altitude divides the longest base into 2 parts 11 and 5
By using Pythagoras theorem in the right angle Δ
∴ The altitude = [tex]\sqrt{(12)^{2}-(11)^{2}}=\sqrt{23}[/tex] = 4.795 ≅ 4.8
