# Unit 3 test parallel and perpendicular lines answer key pdf

Asked by wiki @ in Mathematics viewed by 200 People

Angles can be congruent based n several theorems; some of these theorems are: corresponding angles, vertical angles, alternate exterior angles and several others.

The values of x and y are:

• 5.
• 6.
• 7.
• 8.
• 9. and
• 10. and
• 11. and
• 12. and

Question 5:

Angles (9x + 2) and 119 are alternate angles.

Alternate angles are equal. So, we have:

Subtract 2 from both sides

Divide both sides by 9

Question 6:

Angles (12x - 8) and 104 are interior angles.

Interior angles add up to 180. So, we have:

Collect like terms

Divide both sides by 12

Question 7:

Angles (5x + 7) and (8x - 71) are alternate exterior angles.

Alternate exterior angles are equal. So, we have:

Collect like terms

Divide both sides by 3

Question 8:

Angles (4x - 7) and (7x - 61) are corresponding angles.

Corresponding angles are equal. So, we have:

Collect like terms

Divide both sides by -3

Question 9:

Angles (9x + 25) and (13x - 19) are corresponding angles.

Corresponding angles are equal. So, we have:

Collect like terms

Divide both sides by -4

Angles (17y + 5) and (13x - 19) are supplementary angles.

So, we have:

Substitute 11 for x

Subtract 5 from both sides

Divide both sides by 17

Question 10:

Angles (3x - 29) and (6x - 7)  add up to 180

So, we have:

Collect like terms

Divide both sides by 9

Angles (3x - 29) and (8y + 17) are supplementary angles.

So, we have:

Substitute 24 for x

Collect like terms

Divide both sides by 8

Question 11:

Angles (7x - 23) and (49 + 3x) are corresponding angles

So, we have:

Collect like terms

Divide both sides by 4

Angles 3x and (11y - 1) are corresponding angles.

So, we have:

Substitute 18 for x

Collect like terms

Divide both sides by 11

Question 12:

Angles (5x - 38) and (3x - 4) are corresponding angles

So, we have:

Collect like terms

Divide both sides by 2

Angles (7y - 20) and (5x - 38) are angles at the other legs of a right-angled triangle.

So, we have:

Substitute 17 for x

Collect like terms

Divide both sides by 7
