Romashka-Z-Leto [24]

Answer:

The answer to your question is b = 11.31 cm or 8 $\sqrt{2}$ cm

Step-by-step explanation:

Data

hypotenuse = 18 cm

one leg = 14 cm

second leg = ?

Process

1.- Use the Pythagorean Theorem to solve this problem

c² = a² + b²

c = hypotenuse

a = longer leg

b= shorter leg

2.- Substitution

18² = 14² + b²

-Solve for b

b² = 18² - 14²

-Simplify

b² = 324 - 196

b² = 128

-Find the prime factors of 128

128 2

64 2

32 2

16 2

8 2

2 2

128 = 2⁶2¹

-Result

b = 11.31 or 8 $\sqrt{2}$
