Answer:
The second one is the right one
Hi there! :)

Recall that the sum of all angles in a triangle = 180°.
Therefore:
34° + 24° + x° = 180°
Combine like terms and subtract:
58° + x° = 180°
x = 180° - 58°
x = 122°
<span>17x-2=7x+8
We simplify the equation to the form, which is simple to understand
<span>17x-2=7x+8
We move all terms containing x to the left and all other terms to the right.
<span>+17x-7x=+8+2
We simplify left and right side of the equation.
<span>+10x=+10
We divide both sides of the equation by 10 to get x.
