Help me with this someone

7 is 29

8 is 37

Step-by-step explanation:

For 7 the sides are equal to eachother, so you need to do 20 = x - 9, giving x = 29

For 8 the angles are equal to eachother, so you need to do 60 = x + 23, giving x = 37

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
