Answer:
3
Step-by-step explanation:
Theorem:
If two secants intersect outside a circle, then the product of the length of the exterior segment of one secant and the length of that secant equals the product of the corresponding parts of the other secant.
In this case:
10 × (10 + 5x + 2) = 9 × (9 + 7x)
10(5x + 12) = 9(7x + 9)
50x + 120 = 63x + 81
-13x = -39
x = 3
<u>x = 3</u>
Equating the secants :
2,893
divide 3 by 8679
hope this helps:)
the third answer is correct. hope I helped
42m2
9x4=36m2
3x2x0.5=3m2x2=6m2
36+6=42m2
