x = 68º
Step-by-step explanation:
This trapezoid is a quadrilateral. All degrees in a quadrilateral have to add up to 360º.
76º + 135º + 81º + xº = 360º
292º + xº = 360º
xº = 360º - 292º
xº = 68º

Answer: $37
Step-by-step explanation:
The remaining balance, B (in dollars), on the card after buying x prints is given as $50.00 - 0.15x.
Therefore, the remaining balance on the card if Jane bought 20 prints will be:
= $50.00 - 0.15x.
= $50.00 - 0.15(20)
= $50.00 - $3.00
= $47.00
