Answer:

80°

Step-by-step explanation:

The sum of the angles of a triangle is always 180°.

∴ 2x + 3x + 5x = 180°

10x = 180°

x = 180 / 10

x = 18

The biggest angle = 5x

= 5 * 18

= 90°

AURORKA [14]

The change of population per year is 1,900

We'll start by subtracting; 41,600-24,500= 17,100
Then we'll divide 17,100 by 9 because there is a 9 year difference between 2003 and 2012.
17,100/<span>9=1,900</span>
