tolong dong jawab no 31-36,makasihh :)

31.)
sudut CDE = 90°
sudut ABC = 180° - 90° - 53° = 37°
sudut DEC = 37°

• Jawaban : D

************************************************
32.)
3x - 5° = 82°
3x = 87
x = 29°

• Jawaban : D

************************************************
33.)
sudut p + sudut q = 180°
5x + 4x = 180°
9x = 180°
x = 20°

sudut r = sudut q
sudut r = 4x = 4 × 20° = 80°

• Jawaban : B

************************************************
34.)
3x + 1 = 52 + 90
3x + 1 = 142
3x = 141
x = 47°

• Jawaban : A

************************************************
35.)
sudut BAC = 180° - 75° - 75° = 30°

sudut ACD = sudut BAC
sudut ACD = 30°

• Jawaban : A

************************************************
36.)
sudut RQT = 180° - 90° = 90° ÷ 2 = 45°
sudut PQT = 90° + 45° = 135°

sudut QRS = sudut PQT = 135°

• Jawaban : D
