What is the value of a to the nearest tenth? (geometry)

12.9

7.5

17.5

15.2

A. 12.9

Step-by-step explanation:

We have been given a circle and we are asked to find the measure of segment 'a'.

We will use intersecting chords theorem to solve our given problem. This theorem states that when two chords intersect inside a circle, then product of segments on each chord are equal.

Using above theorem, we can set an equation as:

Dividing both sides by 35, we get

Therefore, the value of 'a' is 12.9 and option A is the correct choice.

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
