Question 315517
2 meters is 200 cm.

Let h = height of man

h^2 + 120^2 = 200^2

h^2 + 14,400 = 40,000

h^2 = 40,000 - 14,000

h^2 = 26,000

sqrt{h^2) = sqrt{26,000)

h = 161.245155 cm

NOTE: sqrt = square root

NOTE: 161.245155 cm means the man is about 5.3 feet tall.

NOTE: 161.245155 cm = 1.61245 meters (in case you need the height of the man in terms of meters).
