Answer 1

Answer:

(c) 2cm

Step-by-step explanation:

given:

OB= 5cm

AB=AC = 6cm

BM = CM ( as AO bisects BC at M)

R.T.P:

find OM

Proof:

in ∆ OBM

OB = 5cm

BM = 6cm

therefore, OM = 2cm

Answer 2

Step-by-step explanation:

given that

$given \: that \\ r = 5cm \\ ab = ac = 6cm \\ = > oa = 5cm(radius) \\ m < amc = 90deg \\ = > mc = \sqrt{ {6}^{2} - {5}^{2} } (pythagorean \: triplate) \\ = 36 - 25 \\ = 11cm \\ = > bc = 11 \times 2 = 22cm \\ oa = 5cm \\ = > om = 5 - \binom{22}{11} = 5-2=3cm$

hope it Help you
