Answer:
There would be 7 groups of students because 56 divided by 8 students gives you 7 groups.
Step-by-step explanation:
The answer is 24
Working out:-3+15=12
12x2=24
5x (-2) = -8
-10x = -8
10x = 8 ( omitting negative on both sides).
x = 8/10
x = 4/5
Measure four is equal to 38 degrees because it is corresponding exterior angle since all the lines are cute by the same transversal and are parallel
16= 32 =48. 72- 48 = 24. The third side of the triangle is 24! Hope this helps, have a great day! :)
