<A = 30°.

Step-by-step explanation:

Name the triangle ABC.

Here, <B is forming linear pair with 130°.

Thus <B = 180 - 130 = 50°

<C is oppsite angle to 8x - 4.

Thus, <C = 8x - 4

We know that sum of angles of triangle is 180°.

THUS,

So, Putting x = 12 in 3x - 6,

Thus , <A = 30°.

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

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
