Answers

Answer 1

Answer:

5:5 or 7:3

Step-by-step explanation:

Step-by-step explanation:

If we get 2 blue marbles and put 2 green, than things will stay like this:

If there are 5 blue marbles, there'll be 5 green marbles.

If we get 2 green marbles and put 2 green, than things will stay like this:

If there are 7 blue marbles, there'll be 3 green marbles.

Answers

Answer:

89 meters

Step-by-step explanation:

We know it's 9 + "the height of the triangle".

Fortunately, the height of the triangle (let's call it y) can be computed from:

y^2 + 18^2 = 82^2 (Pythagoras theorem).

y^2 = 82^2 - 18^2 = 6724 - 324 = 6400

y = 80 (or y = -80 but it doesn't make sense in geometry).

so x = y + 9 = 89;
