If l/m find the value of x and the value of y.

The measure of x and y are 45° and 45° respectively.

Step-by-step explanation:

From the figure, it can be seen that the line l is parallel to line m, and x is the angle made between the horizontal axis and the vertical axis, therefore the measure of the angle x will be 90°.

Using the straight line property, we get

Substituting the value of x in the above equation , we get

Therefore, the measure of x and y are 45° and 45° respectively.

step-by-step explanation:

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
