Answer 1

Penjelasan dengan langkah-langkah:

Soal 1

< P = 180° - < Q

< P = 180° - 112°

< P = 68°

Soal 2

a) 197' = 197/60 = 3° 17'

b) 3890" = 3890/3600 = 1° 290/60 = 1°4'50"

Soal 3

2c = 80°

c = 80/2

c = 40°

2b = 180° - 80°

2b = 100°

b = 100/2

b = 50°

2a + 30 = 2b

2a + 30 = 100

2a = 100 - 30

2a = 70

a = 70/2

a = 35°
