Find the value of x, plz help me soon it’s due in a few mins

The value of x is 13°

Step-by-step explanation:

Given: m || n

For a straight line = 180°

Now, by exterior angle

(7x - 1)° + (8x - 14)° = 180°

7x - 1° + 8x - 14° = 180°

15x - 15° = 180°

Now, add 15° both side we get,

15x - 15° + 15° = 180° + 15°

15x = 195°

Now, divide both side by 15

15x/15 = 195°/15

x = 13°

Thus, The value of x is 13°

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
