A ladder leans up against the side of a house. The ladder is 5 m tall. If the foot of the ladder is 1 m from the side of the house, how high up the house does the ladder reach?

= 2√6

Step-by-step explanation:

a² + b² = c²

1 + b² = 25

b² = 24

b = ±√24

b = ±2√6

We can forget about the minus answer because you cannot have a negative length. That does not make sense.

Please mark me brainliest.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
