Answer:
x = 30 degrees
Step-by-step explanation:
Since the lines are parallel, these angles can be seen as vertical angles, which are always the same as their opposite. Therefore,
75 = 2x + 15
To solve this, you would subtract 15 from both sides, getting you closer to finding x.
75 = 2x + 15
-15 - 15
60 = 2x
Lastly, you would divide both sides to get your value for x.
60 = 2x
/2 /2
30 = x
Answer:
15.12
Step-by-step explanation:
Cost of meal = $20
Discount (coupon) = 30%
Amount of discount = 30% of $20
= 30/100 * 20
= 0.3 * 20
= $6
Amount paid after discount= initial cost of meal - discount
= $20 -$6
= $14
Sales tax =8%
Amount of sales tax = 8% of $14
= 8/100 * 14
= 0.08 * 14
= $1.12
Total amount paid = Amount paid after discount + Amount of sales tax
= $14 + $1.12
= 15.12
C) $51.53
