Question

f

Answer 1

You should start by formulating the given relations into formulas.

Answer 2

For example the edges AB and BC are marked, meaning they have the same length:
$$|AB| = |BC|$$

Answer 3

you can't find a specific value for x, but what you can do is this

the side opposite the angle 2x (which is 22) is smaller than the side opposite the angle 34 degrees (which is 30)

So we know that 2x must be less than 34 degrees (since 22 < 30)

we also know that 2x > 0 because all angles are positive

so

0 < 2x < 34

solve for x
