OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.

The measure of angle N is 141°.
Step-by-step explanation:
From the given figure it is noticed that the angle 39° and angle N lies on a straight line. It means both angles are supplementary angles.
If two angles are known as supplementary angles, then their sum is 180°.
Since angle 39° and angle N are supplementary angle, therefore their sum is 180°.

Subtract 39 from both sides.


Therefore the measure of angle N is 141°.
