The hypotenuse of a right triangle is 20 centimeters, and the shorter leg is 12 centimeters. Find the length of the other leg. 2
cm 4 cm 16 cm
2 answers:
If the shorter leg is 12 the only answer larger than 12 is 16.
A² + b² = c² ⇒ pythagorean theorem
a + b are the legs
c is the hypotenuse
12² + b² = 20² 144 + b² = 400
144 + b² = 20² -144 - 144
-----------------------------
b² = 256
√b² = √256
b = 16
