Answer:

The height of the blue spruce was 45.

Step-by-step explanation:

(160+320+100+110+200+220+x)/7 = 165

(1110+x)/7 = 165

Multiply both sides by 7:

1110 + x = 1155

Subtract 1110 from both sides:

x = 45

Well I'd say it's any number before or after 11. Since it says 2 more tens it could be 31 by adding. You can also use algebra to help you.
