a)
90° - 75° = 15°
b)
90° - 39° = 51°
c)
90° - 40,5° = 49,5°
d)
90° - 71,3° = 18,7°

2]
a)
180° - 23° = 157°
b)
180° - 98° = 82°
c)
180° - 83,2° = 96,8°
d)
180° - 134° = 46°

a)
sudut RQT dan sudut PQS
b)
< PQS = 180° - < SQT
< PQS = 180° - 56°
< PQS = 124°

4]
< B = 90° - < A
< B = 90° - 32°
< B = 58°

5]
< PQS + < SQT + < TQR = 180°
90 + x + 16 + 5x - 58 = 180
6x + 48 = 180
6x = 180 - 48
6x = 132
x = 132/6
x = 22

a)
< SQT = (x + 16)°
< SQT = (22 + 16)°
< SQT = 38°

b)
< TQR = (5x - 58)°
< TQR = (5(22) - 58)°
< TQR = (110 - 58)°
< TQR = 52°
