Correct answer is B. (graph in the first quadrant).
Answer:
C. 10%
Step-by-step explanation:
Given:
Original price of shirt = $42.39
Current sales price of shirt = $38.15
Required:
% decrease in the price of shirt
SOLUTION:
Percentage decrease in price of shirt = change in price over original price, multiplied by 100%
Change in price = original price - current price = $42.39 - $38.15 = $4.24
% decrease = 


% decrease 
Answer: 1. False. [∠XFG is lying between the one side and the line extended to the next side of the triangle, therefore it is an exterior angle.]
2.True. [∠EFG is lying between the two sides of the ΔEFG, therefore it is an interior angle of the triangle]
3.True. [∠FEZ is lying between the one side and the line extended to the other side of ΔEFG ]
4.False. [∠YGE is a straight line it is between the one side and the line extended to the same side ∴ it cannot be an exterior angle of the triangle ]
5. True.[∠EGF and FGY together make a straight line therefore they are supplementary angles]
6.False.[∠FEG and ∠FGE are both the interior angles of a triangle and we know that for supplementary angles they should lie on the same line or together make a straight line]
