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
