Ответ:
43 - 2x = 12x +1
43 - 1 - 2x = 12x + 1 - 1
42 - 2x = 12x
42 - 2x + 2x = 12x + 2x
42 = 14x
42 / 14 = 14x / 14
x = 3
WY = 43 - 2(3)
WY = 37
Step-by-step explanation:
1. since both segments from the same external point are tangent, they are congruent, so we can set them equal to each other.
2. subtract one from both sides
3. subtract two from both sides
4. divide to get the variable itself.
5. take the length of WY and replace x by its value to find the measure of WY.
