Answer:
-24
Step-by-step explanation:
Answer:
2(x+10) = 3x-30 (reason: vertical angles are congruent)
2x+20 = 3x-30
20 = 1x-30
1x = 20+30
1x = 50
x = 50
Yes, the student's theory is correct, because the survey shows that the seventh graders spend more time playing games on the weekend than the eighth graders.
38 degrees
x+52=90
90-52=36
Therefore, angle 2 equals 36 degrees
