In a right triangle the sum of its right angle and one of the acute ones is 102 °. how much does the other acute angle measure?

168 °

Step-by-step explanation:

When acute is 102 then the inner angle is 180°-102°=78°

For a right angle triangle, one side is 90° degrees and the sum of all angles is 180°

The other inner angle will be

180°-90°-78°=12°

The other acute will be 180-12=168 °

< 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
