The Brainliest Answer!

so , oa = 17 cm as ad is diameter and oa is radius

in triangle opa

oa²=op²+ap²

17²=op²+15² [ as op is pependicular it bisects ab it is the theorem]

√289-225=op

op=8 cm

radius = 34/2 = 17cm

ab is the chord of length 30 cm

AP= 15 cm (perpendicular from the chord bisects the chord)

OA² = AP² + OP²

OP² = OA² - AP²

OP² = 15² - 17²

OP² = 225 - 289

OP² = 64cm

OP = 8 cm

So the distance of the chord from the circle is 8 cm
