​

Answer 1

lenght indicated appear to be tangent

Answer 2

9514 1404 393

Answer:

A) 15

Explanation:

The angle where the tangent meets the radius is 90°, so the Pythagorean theorem applies to this right triangle.

?² +8² = 17²

?² = 289 -64 = 225

? = √225 = 15

The unknown side length is 15.
