Verified answer

REMEMBER

When two parallel lines intersect a transversal line.

• corresponding angles are congruent,
• alternate interior angles are congruent,
• alternate exterior angles are congruent,
• consecutive interior angles are supplementary or a pair of angles that have a sum is 180°

====================================

Questions:

15. if m<1=100 degrees then m<5 =

a. 60 degrees b. 80 degrees c. 100 degrees d. 110 degrees

16. if m<2=80 degrees then m<6 =

a. 110 degrees b. 100 degrees c. 90 degrees d. 0 degree

17. if m<3=105 degrees then m<7 =

a. 105 degrees b. 95 degrees c. 85 degrees d. 75 degrees

18. if m<4=75 degrees then m<8 =

a. 75 degrees b. 85 degrees c. 95 degrees d. 105 degrees

EXPLANATION:

• Noticing that all the questions from 15-18 , the angles are consecutive interior/exterior angles , so the sum of the angles is 180°.

We will just subract the angles to 180° to get the answer :))

ANSWER

15. B (80°)

16. B (100°)

17. D (75°)

18. D (105°)
