5/6 because 5/6=0.80 and 2/3=0.66
Answer: unit
Step-by-step explanation:
Since Here Δ ABC is a isosceles triangle.
Also, and
Thus, ∠ ADH = 90°
That is, Δ ADH is the right angle triangle.
In which, AD = a unit and HD = b unit
And, By the definition of Pythagoras theorem,
⇒
⇒
Since, the perimeter of a triangle = sum of the all sides of the triangle.
Therefore, perimeter of ΔADH = AD + DH + AH
= unit
