Question

4. A right triangle has one leg.

measuring 15 meters and a
hypotenuse measuring 25 meters.
How long must the other leg of the
triangle be?
A 12 meters
B 15 meters
C 20 meters
D 24 meters

Answer 1

a^2 + b^2 = c ^2

a = first leg

b = second leg

c = hypothenuse

225 + b^2 = 625

b^2 = 400 -> b = 20 meters
