6x+30 = 180
6x = 150
x = 25
8. 2x+3x+4x = 180
9x = 180
x = 20... lancip? idk
9. besar sudut BCA = CBA = (180-70) ÷ 2 = 110÷2 = 55°
10. PS = PR jadi sudut PSR = sudut PRS
sudut SPR = 180-65-65 = 50°
sudut PRQ = 180-65 (karena berpelurus) = 115
sudut RPQ = sudut PQR = (180-115) ÷ 2 = 32,5°
sudut SPQ = sudut SPR + sudut RPQ = 50+32,5 = 82,5°
