Answer:
x = 10√2 cm
Step-by-step explanation:
Using,
A = 1/2bh.............. Equation 1
From the diagram,
Since: Line AB = Line AC.
Where A = Area, b = h
From the question,
Given: A = 50 cm
Substitute into Equation 1
50 = (h²)/2
h² = 50×100
h² = 100
h = √100
h = 10 cm.
There AB = AC = 10 cm
Applying pythagosras theorem,
x² = 10²+10²
x² =100+100
x² = 200
x = √200
x = 10√2 cm
