X would equal 70°.

For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.

I hope this helps!

Answer:

$x = 0$

Step-by-step explanation:

Given

Represent the number with x.

So:

$2 + x + x + x + x + x + x + x + x + x + x = 2$

$2 + 10x = 2$

We want to solve for x

Subtract both sides by 2

$2 - 2 + 10x = 2 - 2$

$10x = 0$

Solve for x

$x = \frac{0}{10}$

$x = 0$

No other number aside 0, satisfy the property.
