Problem 1
The two angles 6x and 30 are vertical angles, so they are congruent or the same in measure.
6x = 30
x = 30/6
x = 5 is the answer
====================================================
Problem 2
The two angles form a straight angle which is 180 degrees. We consider them a linear pair (since they are adjacent and supplementary).
So,
5x+(3x+12) = 180
8x+12 = 180
8x = 180-12
8x = 168
x = 168/8
x = 21 is the answer
The greatest common factor is 2
Answer:
681
Step-by-step explanation:
5x6=30
30x30=900
2x6=12-10=2
900+2=902
5x3=15
15x15=225
2x3=6
6-10=-4
225-4=221
902-221=681
