7. A

8. C

Penjelasan dengan langkah-langkah:

7. <BOC = 2 x <BAC

= 2 x 53°

= 106°

<COD = 180° – <BOC

= 180° – 106°

= 74°

8. <OML = <MLO = 39° (∆ sama kaki)

<MLK = 1/2 <MOK

= 1/2 x 180°

= 90°

<MOL = 180° – 39° – 39°

= 102°

<KOL = 180° – <MOL

= 180° – 102°

= 78°

<MKL = 180° – <KML – <MLK

= 180° – 39° – 90°

= 51°

<MKL + <KOL = 51° + 78°

= 129°
