<u>Solution-</u>
If the lines are parallel, then the alternate interior angles are congruent.
As the sum of measures of the two alternate interior angles = 210°
⇒ Measure of one alternate interior angles = 105°

Since a straight angle contains 180º, the two angles forming a linear pair also contain 180º when their measures are added (making them supplementary).


Answer:
Step-by-step explanation:
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
