Matematika Hal 171

1.
a. <A = 45°

<B = 60°

<C = 75°

Jumlah : 45° + 60° + 75° = 180°

b. <A = 110°

<B = 40°

<C = 30°

Jumlah : 110° + 40° + 30° = 180°

c. <A = 90°

<B = 55°

<C = 35°

Jumlah : 90° + 55° + 35° = 180°

d. <A = 60°

<B = 60°

<C = 60°

Jumlah : 60° + 60° + 60° = 180°

e. <A = 30°

<B = 115°

<C = 35°

Jumlah : 30° + 115° + 35° = 180°

2.
a. 180° - 95° - 30° = 55°

b. 180° - 20° - 35° = 125°

c. 180° - 30° - 100° = 50°

d. 180° - 55° - 55° = 70°

e. 180° - 40° - 90° = 50°
