Question

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

Answer 1

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

Answer 2

#4

Apply Pythagorean theorem

• H²=P²+B²
• H²=4²+5²
• H²=16+25
• H²=41
• H=√41cm

#5

If base

• √17²-15²
• √8²
• 8

If Hypotenuse

• √17²+15²=√514
