Which of these expressions demonstrates the identity property? Check all that apply. 25(0) = 25
25(1) = 25
25 + 0 = 25
25 +1 = 25

25(1) = 25

25 + 0 = 25

Step-by-step explanation:

The identity property for addition is 0 because 0 added to any number is the number itself.

The identity property for multiplication is the number 1 because  1 times any number is the number itself.

< 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

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
