You can use Pythagreos theorem to determine it!
Pythagreos theorem is a^2 + b^2 = c^2
1) 4^2 + 4^2 = 6^2
16 + 16 = 36
32 = 36 (So this is not a right-angled triangle )
2) 16^2 + 12^2 = 20^2
256 + 144 = 400
400 = 400 (Sp this is a right-ngled triangle)

Answer:
x = 1
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 5 when x = 3
k = yx = 5 × 3 = 15, thus
y =
← equation of variation
When y = 15 then
15 =
( multiply both sides by x )
15x = 15 ( divide both sides by 15 )
x = 1
It is the right answer........
