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]
Easy, 12-8=4+3=7+5=12 So, he had 12 books before last week
The pattern is that you are dividing by 3.
Therefore, to work out the next three numbers, you need to divide the last number by 3.
So you'd do:
1/9 ÷ 3 = 1/27
1/27 ÷ 3 = 1/81
1/81 ÷ 3 = 1/243
Therefore, the next three numbers are 1/27, 1/81, and 1/243.
