That line that is made out of angles 1 and 2 is straight. What we know about straight lines is that they're 180°. This means that ∠1 and ∠2 are supplementary, adding up to 180°.
∠1 + ∠2 = 180
∠1 = (x + 81)
∠2 = (2x)
(x + 81) + 2x = 180
3x + 81 = 180
3x = 99
x = 33
The answer is x = 33.
Step-by-step explanation:
65° + 57° + x = 180° ( the sum of angle of triangle is 180° )
122° + x = 180°
x = 180° - 122°
x = 58°
hence the answer is 58°....

C
because if you look at where the unmarked side is divided, the one you’re supposed to find is obviously bigger than the other.
