Step-by-step explanation:
1. Non-zero digits are significant
2. Zeroes between two significant numbers are significant
3. Trailing zeroes are significant
0.0102 has 3 <span>significant figures
1 and 2 are non-zero digits (Rule 1)
0 between 1 and 2 is zero between </span>two significant numbers (Rule 2)
Answer:
given chord AB=chord CD
L and M are the mid-points of two equal chords AB and CD of a circle
we have
(Equal chords are equidistant from the centre)
In ∆ OLM
OL = OM
<OLM= <OMLbase angles
opposite to equal sides of a A
But <OLA = <OMC(Each = 90°being perpendicular )
On adding
<OLM+<OLA = <OML+<OMC
=<ALM = <CML
