The answer is D
if the legs are 5 and 4 cm the equation to find the hypotenuse would be 5^2+4^2=c^c
5 squared is 25 and 4 squared is 16 that gives you 41, normally you would square root the 41 but it gives you a decimal number

Answer:

  • 4) √41 cm
  • 5) 8 cm or √514 cm

Step-by-step explanation:

<h3>#4</h3>

<u>According to Pythagorean:</u>

  • c² = a² + b²
  • c² = 4² + 5² = 16 + 25 = 41
  • c = √41
<h3>#5</h3>

Two sides are 15 cm and 17 cm

<u>If the third side is hypotenuse, its length is:</u>

  • c = √(15² + 17²) = √514 cm

<u>If the third side is leg, its length is:</u>

  • a = √(17² - 15²) = √64 = 8 cm
