Ingat ! sudut yang menghadap diameter (sudut ABC) pasti sudutnya 90°jadi,
∠BCA + ∠ABC + ∠CBA = 180° (segitiga)
25° + 90° + x = 180°
115° + x = 180°
x = 180° - 115°
= 65° (D)
Verified answer
Sudut Segitiga Siku siku=90 derajatSudut Segitiga=180 derajat
<ABC+<BCA+<CBA=180
90+25+<CBA=180 Derajat
115+<CBA=180 Derajat
<CBA=180-115 Derajat
<CBA=65 Derajat ( D )
