Question

I literally have no clue what this unit is about so help

Answer 1

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 2

Answer:

• 4) √41 cm
• 5) 8 cm or √514 cm

Step-by-step explanation:

#4

According to Pythagorean:

• c² = a² + b²
• c² = 4² + 5² = 16 + 25 = 41
• c = √41

#5

Two sides are 15 cm and 17 cm

If the third side is hypotenuse, its length is:

• c = √(15² + 17²) = √514 cm

If the third side is leg, its length is:

• a = √(17² - 15²) = √64 = 8 cm
