Answer:
Step-by-step explanation:
According to intersecting secants theorem:
Substitute values and solve for x:
- (x - 1)(x - 1 + 7) = 12²
- (x - 1)(x + 6) = 144
- x² - 5x - 6 = 144
- x² - 5x - 150 = 0
- x² - 15x + 10x - 150 = 0
- x(x - 15) + 10(x - 15) = 0
- (x - 15)(x + 10) = 0
- x = 15
- x = -10 (ignored as negative)
