jawaban pertanyaan berikut

<p><strong>a) </strong>nilai x = ?</p><p>&nbsp; &nbsp; &nbsp;karna ∠CBA dan ∠CBD &nbsp;itu garis lurus, jadi total mereka = 180 °</p><p>&nbsp; &nbsp; &nbsp;jadi x + 5x = 180&nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 6x = 180</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; x = 30°</p><p><strong>b)&nbsp;</strong> ∠HAC =?</p><p>&nbsp; &nbsp; &nbsp; &nbsp;karna ∠HAC dan ∠CAB itu juga garis lurus, jadi total mereka = 180 °</p><p>&nbsp; &nbsp; &nbsp; &nbsp;∠HAC + ∠CAB = &nbsp;180</p><p>&nbsp; &nbsp; &nbsp; &nbsp;∠HAC + 40 = &nbsp;180</p><p>&nbsp; &nbsp; &nbsp; &nbsp; ∠HAC = 140°</p><p><strong>c) </strong>∠ABC = x = 30°</p><p><strong>d) ∠</strong>BAC = ?</p><p>&nbsp; &nbsp; &nbsp;karna 1 segitiga itu 180° jadi&nbsp;</p><p>&nbsp; &nbsp; &nbsp;<strong>∠</strong>BAC = 180-30-40</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 110°</p><p><strong>e) &nbsp;</strong>∠DBC= 5x = 150°</p><p><strong>f)&nbsp;</strong> karna ∠ACG berseberangan dalam sama ∠CAB jadi nilainya sama&nbsp;</p><p>&nbsp; &nbsp; &nbsp; ∠ACG = 40°</p><p><strong>g) </strong>∠FCB = itu sudut lurus jadi = 180°</p><p><strong>h) </strong>∠GCF = 110° karna bertolak belakang sama ∠BCA jadi nilai sama</p><p><strong>i) </strong>∠FCE = sama kaya ∠DBC = 150°</p><p><strong>j) &nbsp; ∠</strong>FCE berpelurus sama ∠GCF</p><p>&nbsp;</p><p><strong>SELESAII YEYYY !!!!!!</strong></p>
