E: Brought in its wake much-needed safety legislation.

Step-by-step explanation:

The Triangle Shirtwaist fire occurred on March 25, 1911. It is considered as one of the deadliest fire accidents in U.S. history.

This accident unfolded the truth of poor working conditions in factories and other workplaces that finally led to labor reforms.

The fire led to introduce the safety legislation, which required improved factory safety standards for workers.

< 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
