Complexity=5, Mode=numSupp

Find the value of 'x'. Diagrams are not always to scale.

#	Problem	Correct Answer	Your Answer
1		x =
Solution The two angles form a line so they are supplementary angles. The sum of supplementary angles is 180 degrees. 80 + x = 180 x = 180 - 80 x = 100

2		x =
Solution The two angles form a line so they are supplementary angles. The sum of supplementary angles is 180 degrees. 65 + x = 180 x = 180 - 65 x = 115

Complexity=8, Mode=varSupp

Find the value of 'x'. Diagrams are not always to scale.

#	Problem	Correct Answer	Your Answer
1		x =
Solution The two angles form a line so they are supplementary angles. The sum of supplementary angles is 180 degrees. 5x + 13x = 180 18x = 180 18x ÷ 18 = 180 ÷ 18 x = 10

2		x =
Solution The two angles form a line so they are supplementary angles. The sum of supplementary angles is 180 degrees. 10x + 26x = 180 36x = 180 36x ÷ 36 = 180 ÷ 36 x = 5

Complexity=10, Mode=distAng

Find the value of 'x'. Diagrams are not always to scale.

#	Problem	Correct Answer	Your Answer
1		x =
Solution The angle marked as 50 degrees forms a line with the angle next to it. They are supplementary angles. Let y be this supplementary angle. 50 + y = 180 y = 180 - 50 = 130 The angles of a triangle add up to 180 degrees.. x + 130 + 28 = 180 x + 158 = 180 x = 22

#	Problem	Correct Answer	Your Answer
2		x =
Solution The angle marked as 41 degrees forms a line with the angle next to it. They are supplementary angles. Let y be this supplementary angle. 41 + y = 180 y = 180 - 41 = 139 The angles of a triangle add up to 180 degrees.. x + 139 + 23 = 180 x + 162 = 180 x = 18

Complexity=20

Find the value of 'x'. Diagrams are not always to scale.

#	Problem	Correct Answer	Your Answer
1		x =
Solution The two angles form a line so they are supplementary angles. The sum of supplementary angles is 180 degrees. 29 + x = 180 x = 180 - 29 x = 151

#	Problem	Correct Answer	Your Answer
2		x =
Solution The angle marked as 46 degrees forms a line with the angle next to it. They are supplementary angles. Let y be this supplementary angle. 46 + y = 180 y = 180 - 46 = 134 The angles of a triangle add up to 180 degrees.. x + 134 + 33 = 180 x + 167 = 180 x = 13
