current skill $\
$what is the value of x?\

Explanation:

Step1: Identify supplementary angles

Angles 7 and the 107° angle are supplementary (they form a linear pair), so angle 7 = 180° - 107° = 73°. But also, angle 7 and \(6x + 5\) are vertical angles? Wait, no, actually, angle 7 and \(6x + 5\) – wait, no, let's check again. Wait, angle 7 and the angle labeled \(6x + 5\) – wait, no, the angle with measure 107° and angle 7 are supplementary, so angle 7 = 180 - 107 = 73°. Then, angle 7 and \(6x + 5\) – wait, no, actually, the angle \(6x + 5\) and the angle adjacent to 107° (angle 6) – wait, no, maybe angle 7 and \(6x + 5\) are equal? Wait, no, let's see: the two lines are parallel? Wait, the two transversals? Wait, no, the two vertical lines (the two slanted lines) – wait, maybe the angle \(6x + 5\) and the angle 107° are related? Wait, no, angle 7 and the 107° angle are supplementary, so angle 7 is 73°. Then, angle \(6x + 5\) and angle 7 – wait, no, maybe \(6x + 5\) is equal to 107°? Wait, no, that can't be. Wait, maybe I made a mistake. Wait, the angle labeled 107° and angle 6: are they supplementary? No, angle 107° and angle 7 are supplementary (linear pair), so angle 7 = 180 - 107 = 73°. Then, angle \(6x + 5\) and angle 7: are they vertical angles? Wait, no, the two slanted lines intersect the horizontal line. So, angle 7 and angle \(6x + 5\) are adjacent? Wait, no, the horizontal line is a straight line, so angle 7 + \(6x + 5\) + angle 3 + angle 1 = 180? No, that's not right. Wait, maybe the two slanted lines are parallel, so corresponding angles are equal. Wait, if the two slanted lines are parallel, then angle \(6x + 5\) would be equal to angle 107°? Wait, no, that would make \(6x + 5 = 107\), then 6x = 102, x = 17. But that seems high. Wait, no, maybe angle \(6x + 5\) and angle 7 are supplementary? Wait, angle 7 is 73°, so \(6x + 5 + 73 = 180\)? No, that would be 6x + 78 = 180, 6x = 102, x = 17. Wait, but maybe the angle \(6x + 5\) is equal to 107°? Wait, let's check: if \(6x + 5 = 107\), then 6x = 102, x = 17. Alternatively, if angle \(6x + 5\) and angle 7 are equal, angle 7 is 73°, so \(6x + 5 = 73\), then 6x = 68, x = 68/6 ≈ 11.33, which is not an integer. So maybe the correct approach is that angle \(6x + 5\) is equal to 107°, so:

Step1: Set up the equation

Assume that \(6x + 5 = 107\) (since they are corresponding angles or vertical angles, maybe the lines are parallel).

Step2: Solve for x

Subtract 5 from both sides: \(6x = 107 - 5 = 102\)

Divide both sides by 6: \(x = \frac{102}{6} = 17\)

Wait, but let's verify. If x = 17, then \(6x + 5 = 6*17 + 5 = 102 + 5 = 107\), which matches the angle 107°, so that makes sense. So the value of x is 17.

Answer:

17
