Answer:
9 sides
Step-by-step explanation:
7y + 2y = 180
9y = 180
y =20
so, 2y, the exterior angle is 2 x 20 = 40

Answer:
The answer is 1,328
Step-by-step explanation:
Let pages written by Tom for a school report = x
Pages written by Jen for school report= 10 x
Pages written by Tom + Pages written by Jen = 396
→ x + 10 x = 396
→ 11 x =396
Dividing both sides by 11, we get
→ x =36,
Pages wrote by Tom= 36 pages
Pages wrote by Jen = 36 × 10=360 pages
