The length of a shadow of a building is 30 m. The distance from the top of the building to the tip of the shadows is 36 m. Find the height of the building.

46.86

Step-by-step explanation:

a^2+b^2=c^2

30^2+36^2=c^2

2196=c^2

Square root both sides

46.86=c

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
