Acarpenter who is installing cabinets uses thin pieces of material called shims to fill gaps. the carpenter uses four shims to fill a gap that is 1.2 centimeter wife. threee of the shims are 0.75 centimeter, 0.125 centimeter, and 0.09 centimeter wide. what is the width of the fourth shim pls show work.

.235

Step-by-step explanation:

Total Distance - Shim 1 - Shim 2 - Shim 3 = Shim4

1.2 cm - 0.75 cm - 0.125 - 0.09 cm = 0.235 cm

2

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
