Pertanyaan

a. Hitunglah nilai p dan q

b. Tentukan besar angle ABD dan angle PQT 

Pembahasan Soal:

a. angle CBD dan angle DBE berpenyiku, maka

table attributes columnalign right center left columnspacing 0px end attributes row cell angle CBD plus angle DBE end cell equals cell 90 degree end cell row cell 36 degree plus 2 p end cell equals cell 90 degree end cell row cell 2 p end cell equals cell 90 degree minus 36 degree end cell row cell 2 p end cell equals cell 54 degree end cell row p equals cell fraction numerator 54 degree over denominator 2 end fraction end cell row p equals cell 27 degree end cell end table 

angle PQT comma space angle TQS comma space angle SQR membentuk garis lurus, maka

table attributes columnalign right center left columnspacing 0px end attributes row cell angle PQT plus space angle TQS plus angle SQR end cell equals cell 180 degree end cell row cell 3 q plus 90 degree plus 2 q end cell equals cell 180 degree end cell row cell 5 q plus 90 degree end cell equals cell 180 degree end cell row cell 5 q end cell equals cell 180 degree minus 90 degree end cell row cell 5 q end cell equals cell 90 degree end cell row q equals cell fraction numerator 90 degree over denominator 5 end fraction end cell row q equals cell 18 degree end cell end table 

Jadi, nilai p equals 27 degree dan q equals 18 degree.

b.Menentukan besar angle ABD

 table attributes columnalign right center left columnspacing 0px end attributes row cell angle ABD end cell equals cell angle ABE plus angle DBE end cell row blank equals cell 90 degree plus 2 straight p end cell row blank equals cell 90 degree plus 2 left parenthesis 27 degree right parenthesis end cell row blank equals cell 90 degree plus 54 degree end cell row blank equals cell 144 degree end cell end table 

Menentukan besar angle PQT

table attributes columnalign right center left columnspacing 0px end attributes row cell angle PQT end cell equals cell 3 q end cell row blank equals cell 3 left parenthesis 18 degree right parenthesis end cell row blank equals cell 54 degree end cell end table 

Jadi, besar angle ABD equals 144 degree dan angle PQT equals 54 degree.
