A triangle with sides 5, 12 and 13 is similar to another with a
circumference of 60. What is the area of the second triangle?

200 square units

Step-by-step explanation:

first you think what 60/3 is and you get 20

then you multiply 20x20 and get 400

then you divide by 2 because to find the area of a triangle you use the formula (lxh)/2

< 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
