Pembahasan

- Nilai - Nilai Sehingga: Jadi,besar penyiku adalah .

- Nilai straight p

$2 straight p degree plus 36 degree equals 90 degree space rightwards arrow space Berpenyiku space space space space space space space space space space 2 straight p degree equals 90 degree minus 36 degree space space space space space space space space space space 2 straight p degree equals 54 degree space space space space space space space space space space space space straight p degree equals fraction numerator 54 degree over denominator 2 end fraction space space space space space space space space space space space space space space straight p equals 27 degree$

- Nilai straight q

$3 straight q degree plus 90 degree plus 2 straight q degree equals 180 degree space rightwards arrow space Berpelurus space space space space space space space space space space 5 straight q degree plus 90 degree equals 180 degree space space space space space space space space space space space space space space space space space space space space 5 straight q degree equals 180 degree minus 90 degree space space space space space space space space space space space space space space space space space space space space 5 straight q degree equals 90 degree space space space space space space space space space space space space space space space space space space space space space space straight q degree equals fraction numerator 90 degree over denominator 5 end fraction space space space space space space space space space space space space space space space space space space space space space space straight q degree equals 18 degree$

Sehingga:

Penyiku space angle PQT equals 90 degree minus angle PQT Penyiku space angle PQT equals 90 degree minus 3 straight q degree Penyiku space angle PQT equals 90 degree minus 3 open parentheses 18 close parentheses degree Penyiku space angle PQT equals 90 degree minus 54 degree Penyiku space angle PQT equals 36 degree

Jadi, besar penyiku angle PQT adalah 36 degree .
