What is the value of x rounded to nearest tenth

Mathematics
1 answer:
Ivahew [28]3 years ago
5 0

Answer:

6.5 cm

Step-by-step explanation:

Here, <em>the tangent line squared is equal to the secant line times the secant line outside the circle</em>.

That is <em>20.2² = 14.7 * (14.7 + 2x)</em> --> it is 2x because the secant goes through <em>the whole circle</em>.

Simplify: <em>408.04 = 216.09 + 29.4x</em>

Subtract: <em>191.95 = 29.4x</em>

Divide: <em>x = 6.528911565</em> ≈ 6.5 cm
