Answer:
122
Step-by-step explanation:
Given information, line t is parallel to line s.
angle 1 and angle 2 are alternate angles and so their measure is equal to each other:
10x + 2 = 12x - 22 transfer like terms to the same side of the equation
2 + 22 = 12x - 10x
24 = 2x divide both sides by 2
12 = x to find the measure of angle 2 replace x with the value we found
12*12 - 22 = 122
