a.Hitunglah nilai p dan q! b.Hitunglah besar

gambar 1 :
90°+p°+36° = 180°
126°+ p° = 180°
p = 180° -126°
p = 54°

90°+38°+2q° = 180°
128° + 2q = 180°
2q = 180 -128
2q = 52°
q = 52 /2
q = 26°

sudut DAB =
90°+54° = 144°

sudut RQS adalah 2(26) = 52°

p = 90 - 36 = 54°
2q = 90 - 38 = 52° 
q = 52 ÷ 2 = 26°

besar ∠DBA = 90 + p = 90 + 54 = 144°
besar ∠RQS = 2q = 52°

semoga membantu ^-^
