Only one (1).
If it had two right angles, they would add up to 180 degrees, and there would be no more degrees left over to make the third angle with.
Answer: 1 right angle

The answer is B
805.48N/m
According to Hookes law
F = Ke
F is the force = mg
F = 2.4×9.8 = 23.52N
e is the extension = 2.92cm = 0.0292m
Force constant K = F/e
K = 23.52/0.0292
K = 805.48N/m
Hence the force constant of the spring is 805.48N/m
